Intel G41 Northbridge; Intel ICH7 Southbridge,
(The Intel ICH7 is also Intel part number 82801GB)http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg
(CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short)http://en.wikipedia.org/wiki/List_of_intel_chipsets#Core_2_chipsets
G41, scroll down towards the bottom of the chart.
Introduced in the last quarter of 2009http://en.wikipedia.org/wiki/PCI_Express#PCI_Express_2.0
The PCI Express 2.0 technology came out January 15, 2007
Means your PCI-Express x16 slot is based on the PCI Express 2.0 technologyhttp://www.newegg.com/Product/Product.aspx?Item=N82E16814121725
The Asus GTX650 graphics card, (No matter which version), is based on the PCI Express 3.0 technology
PCI Express 3.0 technology is Backward Compatible, with PCI Express 2.0 technology,http://en.wikipedia.org/wiki/PCI_Express#PCI_Express_3.0
"PCI Express 3.0 Base specification revision 3.0 was made available in
November 2010, after multiple delays. In August 2007, PCI-SIG announced
that PCI Express 3.0 would carry a bit rate of
8 GigaTransfers per Second, (8GT/s), and that it would be backward compatible with existing PCIe implementations."
PCIe =PCI Express
So yes it will work, AND will work at FULL capacity.
Also your motherboard chipset (Northbridge), will support Intel processors that utilize an LGA 775 processor socket, AND up to an Intel Core2 Quad CPU. (Processor)
DOES TAKE SOME POWER, though!
You need a Power Supply that will not only deliver the necessary Wattage, for the computer system; but also need Up To an additional 150 Watts JUST for the graphics card itself.
Know what happens when you try to under power, a powerful graphics card?
The computer doesn't work
A) The contact pins in the PCI-Express x16 slot, will burn
B) The gold plated contact pins on the bottom, of the graphics card will burn
C) The graphics card requires more power, than the PCI-Express x16 slot can deliver.
A PCI-Express x16 slot can only deliver Up To 75 Watts.
A 6-pin PCI Express power cable is required.
This power cable can deliver Up To 75 Watts.
If there isn't enough power the contact pins, in the 6-pin PCI Express power cable will burn.
So will the contact pins for the power cable, on the graphics card.
The motherboard by itself requires 120 to 150 Watts.
Depending on Processor, Up To 130 Watts.
For each stick of Ram Memory add 25 Watts
25 to 30 for each Optical Drive. (CD/DVD drive)
2 to 3 Watts for each fan; to include the Processor fan, and computer case fans.
Now add 150 Watts for the graphics card.........
