There are many things you need to consider before purchasing a new graphics card.
First you need to know what type of graphic card is compatible with your motherboard and how much space you have inside of the PC tower.
Since newer cards use a lot of power, it is also important to check your PCs power supply.
The simplest way to find out what type of graphic card is compatible to your motherboard is by looking at the expansion slot and power specifications in the motherboards manual.
Locate your motherboard's manual.
If you don't have one then open up your web browser and enter your motherboard or PC's manufacturer's website.
Go to the support page on the manufacturer's website and enter your motherboard's model number.
Download the motherboard's manual from the support page.
Look for the "expansion slot" section in the manual to check the motherboards expansion slot specifications.
If your motherboard uses a AGP expansion slot then write down the version (1.0, 2.0 and 3.0), and the bandwidth (1x, 2x, 4x or 8x).
If your motherboard uses a PCI Express expansion slot then write down the amount of lanes (x1, x4, x8 or x16).
Look for the "Power Supply" specifications in the manual and write down the power supply's voltage (3.3V,5V or 12V).
Determining a compatible graphics card

to find out information on your motherboard. Click the "Mainboard Information" icon, then write down the information next to "Manufacturer" and "Model."
Navigate to the motherboard manufacturer's website.
If you are not sure of the website's URL, enter the manufacturer's name into a search engine to find the company's website.
Go to the support page and enter your motherboard's model.
Download the motherboard's manual or review the specifications.
Search the manual or specifications for "Expansion slot," "AGP" or "PCI Express."
If the expansion slot uses AGP, note the version (AGP comes in 1.0, 2.0 and 3.0), as well as the bandwidth (1x, 2x, 4x or 8x).
If the expansion slot uses PCI Express, note the amount of lanes (x1, x4, x8 or x16).
Search the manual or specifications for "Power," "PSU" or "Power Supply."
Write down the power supply's voltage (3.3V, 5V or 12V) and amp rating (designated by "A").
Not all manufacturers list the amp rating in their documentation, so you may need to contact the manufacturer for more assistance.
Compare the graphics card you want to buy to the motherboard's expansion slot.
AGP cards won't work in motherboards using PCI Express, and vice versa.
Similarly, AGP 3.0 cards won't work in motherboards using AGP 1.0. A PCI Express x8 card will not fit in a PCI Express x1 slot.
Check the voltage and amperage of the video card to the voltage and amperage on your motherboard.
A video card that requires a higher amp rating requires a powerful PSU.
