Bottleneck


In general video games are not very CPU intensive, they mostly rely on your GPU. Your GPU is not grossly newer than your CPU so short answer is no, in most cases your GPU will not be bottlenecked by your CPU.

How to choose an adequate graphic card


A graphics card is mainly composed of a processor, GPU (Graphic Processing Unit), and memory.

The graphics card is in itself a small PC dedicated to graphics applications, independent of the rest of the PC, the only link being the information passing through the port graphic and food.

Choosing a card is based on its needs and its budget:
  • For desktop applications, a map called "entry level" enough;
  • For multimedia applications, a map can read the desired video format is imperative;
  • For 3D video games (and generally all 3D applications), one more powerful is essential.

Structure of a graphics card

The essential component that will determine the performance of the graphics card is the GPU:
A modern GPU is based on different units calculation:
  • Processors Flow
  • Texturing units,
  • Raster units (ROPS).

The most important are the processors flows over the number of processors flow is important, the GPU will be more powerful (for architecture).
The model number on the card is linked to the GPU.

To enable the GPU to store its calculations, there are memory:
  • It varies in quantity:
    • 256 MB enough for the tickets range of previous generations;
    • 512 MB is sufficient for most current cards graphics;
    • 1GB is needed for cards with a very powerful GPU, the GTX 280;
    • Broadly speaking, the more you play in high resolution and filtering enabled, you need more memory.
  • It varies in type:
    • DDR2, DDR3, DDR4 or DDR5: The higher the figure, the greater the memory is fast. His type does not relate to that used for RAM PC: you can have a PC in DDR2 and DDR3 graphics card.
  • Its frequency:
    • Plus it is high, the card is more powerful.

Finally, to link GPU and memory is the memory bus.
The width of this bus is important: it may be 64, 128, 256, 384 and 512 bits: over the bus is large, most trade between the GPU and memory will be rapid. A map to 256-bit bus is efficient at a map of 128-bit bus for the same GP

I have a nvidia geforce 9400 Gt graphics card how can i overclock


Read this...

You're not going to get a lot out of that card, it's pretty stripped down being a 9400. Anyways, download Rivatuner then after it detects your video card it will update your registry which will allow it to manipulate your video card.

You then use it to increase your Memory and Core clocks, and also the shader clock in VERY small steps. Increase it by perhaps 20MHz then try playing the most visually demanding game that you own and play it for like 5 to 10 minutes and watch for anything out of the ordinary. When you've pushed your card too high there are obvious signs, like random pixels flashing across the screen, textures showing up wrong (colours where they shouldn't be), or your game can simply lag or crash.

Also download Speedfan and monitor your GPU temperature closely. See what it idles at normally, then use Rivatuner to increase your fan speed to somewheres around 75% and make sure that the temperatures don't pass 70C.

Overclocking voids warranties and you can damage your graphics card if you push it too hard. You have to be careful and watch for signs that it's being pushed too hard. Also, you have to make sure that you set your clock speeds back to normal when you don't need the extra power. It's easier on your card then running it at 120% or something permanently.

The criterion of a good VGA Card


10 Things you should know before buying a Video Card





Selecting a video card upgrade can be an intimidating task. Unless you've kept up with all the GPU announcements and performance reports, it's practically impossible to know which cards are worth buying.
Graphics processing units, like CPUs, improve year after year, and that means there's a staggering selection of graphics cards available to choose from and retailers just love to place obsolete cards right alongside the latest and greatest. If you're not careful, you could very well end up paying a lot of money for technology that's already a generation behind. Here are 10 things you need to know about video cards before shopping for one.

1. Memory isn't everything
Here's the deal. You need a video card that has a decent amount of memory to play games at high-resolution with quality graphics settings enabled. Good video cards usually have lots of memory because all of that GPU horsepower will go to waste if you don't have enough memory space.
However, the video card manufacturers know that novice buyers look at memory size as one of the main comparison points between different cards, and that's why it's very common to see cards with cheap GPUs sporting 256MB or even 512MB of memory, which is sort of like dropping a 110-horsepower engine into the body of a muscle car. The underpowered card might have some of the right numbers on the spec sheet, but its poor performance will show once the gaming starts.


2. It's all about the GPU
Memory is important, but the real heart of the video card is the graphics processing unit. When you're browsing through video card names, the most important thing to look for is the GPU type, since that little chip is responsible for all of the video card's 3D performance. Today's best GPUs come from Nvidia and ATI, but it's not enough just to buy a video card with a "Nvidia GeForce" or "ATI Radeon" GPU. You also have to pay attention to the model number since Nvidia and ATI label all their cards from the sub-$100, entry-level cards to the AU$800 high-end monsters with the same GeForce and Radeon brand names. Higher model numbers are better, but you should also pay attention to additional modifiers at the end, such as GT, GS, GTX, XT, and XTX, since they often reveal important shader and clock-speed information. Study a few video card reviews or game performance guides to get familiar with the current models to see how they compare.

3. Pipelines, shaders, and clock speeds
You could look at a GPU's clock speed and the pixel pipeline count to get a rough idea of the card's performance level in the early days of 3D acceleration. Today's GPUs have evolved to do much more than brute-force pixel processing. Lighting and other effects that used to take several pipeline "passes" can now run though a shader program to get the same results with fewer passes and less wasted work. GPUs now have specialised processing units dedicated to crunch through complex vertex and pixel-shader programs. Shader units might become an important specification to watch in future video cards as games become more shader-intensive. ATI has recently started reporting the number of shader units it has assigned to each pixel pipeline in its Radeon X1900 XTX line.



For the time being, you can still judge current GPUs by the number of pixel pipelines they have. GPU manufacturers also report vertex pipelines, but we haven't seen any games that bottleneck at the vertex-processing level yet. Entry-level cards usually have four pixel pipelines. Midrange cards have 8 or 12 pipelines, and high-end cards have 16 or more pipelines. Higher clock speeds are always better, but if you're choosing between pipelines or clock speeds, it's usually better to select more pipes over more MHz. Having eight pipelines running at 400MHz is much better than having four pipelines running at 500MHz.
4. Windows Vista and Direct3D 10
Microsoft plans on shipping its newest Windows operating system, Windows Vista, in early 2007. The new OS will feature DirectX 10, an updated collection of functions that software applications can use to access various system resources, including the 3D graphics card. The new version of DirectX incorporates a new version of Direct3D designed to streamline the graphics pipeline by reducing CPU overhead and moving more work to the GPU. Windows Vista will still work with current DirectX 9 video cards, but you'll need a DirectX 10 video card to run DX10-enabled games at the best settings.
We expect Nvidia and ATI to ship their first DX10 cards in the second half of this year, but you don't need to rush out and get one if you're afraid of game-compatibility problems. Game developers understand that it will be several years before the DX10 installation base surpasses the DX9 installation base. All games, including Vista exclusives Halo 3 and Shadowrun, will be DX9 and DX10 compatible for several years after Vista's arrival.
5. It's (almost) always a good time to buy
The fierce competition between Nvidia and ATI has rewarded us with a fast 3D technology development cycle. The GPU manufacturers release a new line of chips every 12 to 18 months, which results in a steady stream of increasingly powerful cards with more and more features. Manufacturers also tweak designs to increase clock speeds and add new features to refresh product lines several months after the initial architecture rollout. Since many new features are forward-looking, such as H.264 high-definition video acceleration and advanced Shader Model support, it might be a year or two before the actual content becomes widely available.
It's always a good time to buy if you don't have to get the best card available. Video card prices fall quickly since new product introductions constantly push older or slightly less powerful hardware into more affordable price ranges. The worst-case scenario is buying a high-end card right before Nvidia or ATI release a new line of GPUs, but even then, you still end up with a very powerful card that will have no problem running the games you want to play for a very long time.
6. You don't need to spend AU$800
The newest top-end cards ship at AU$800 or more, but you can always find several high-performance cards in the AU$350-AU$500 range. This price range usually offers the best performance for the dollar because it includes a mix of current-generation enthusiast-level cards as well as discounted high-end cards from the previous graphics generation. Check out pipeline and clock speed specifications when comparing two cards from different technology generations. If the specs are roughly the same, go with the newer card since it'll have support for more advanced features. Newer chip architectures are also more efficient so you'll get more performance out of the same number of pipelines.
7. Do you have the power?
System power requirements have become a major concern now that video cards have grown into strong, power-sucking behemoths. Video card manufacturers print the power-supply recommendations on the side of the box. The printed number is often slightly higher than actually necessary since it accounts for poor power-supply quality and overloaded systems. Mid- to high-end single cards usually require a 400W or 450W power supply. Requirements for dual-card setups such as a CrossFire Radeon X1900 XTX configuration start at 550W.
8. AGP and PCI Express
Since its introduction two years ago, PCI Express has replaced AGP as the standard graphics slot in currently shipping systems. PCI Express offers two to four times more bandwidth than AGP, and almost all new video cards come in the PCI Express format. The GPU manufacturers throw a bone to AGP system owners once in a while with a new GPU like the Nvidia GeForce 7800 GS, but all the best equipment comes out for PCI Express first.
If your PC system is more than two years old, it probably has an AGP slot. Upgrading to PCI Express will be expensive since you'll need to replace the motherboard, CPU, and memory, but if your system is more than two years old, it might just be the right time to upgrade your entire PC anyway.

This is the video card buyers bible i wll send the other 2 things you should know in a comment...as well as some nice pics and articles.....
I hope this helps...good luck...thanks for rating my effort.....The Fang.

The most annoying problem with MSI FX550-TD256 GeForce


Hi ions.

You were right that digital signature doesn't affect the performance.
I am feeling sorry to tell you that your gpu is old and unable to support many new games
and that's the problem you are facing.

Trust me there is no conflict with your gpu's driver's data, if there had been an conflict the gpu would not have worked at all.

Even the driver's of my brand new Nvidia 280 GTX are not digitally signed by microsoft.
Digital signature means that microsoft has checked that this driver is safe.
The driver will get in the list of digitally signed driver if you update your windows.
