Question about Nvidia Card

[Game_boy]

The site mentioned above does this for under $100. Honestly, anything less than this will not run any games old or new and you might as well buy integrated from Intel. The site recommends the 2600XT over the 8600GT because it leads when AA is off and when AA is on both are unplayable. Get the 2600XT or stick with integrated.

Best PCI-E Card For Under $100: Tie
Radeon HD 2600 XT
Codename RV630
Process 65 nm
Universal Shaders 128
Texture Units 8
ROPs 4
Memory Bus 128 bit
Core Speed MHz 800
Memory Speed MHz 700 (1400 effective)
DirectX / Shader Model DX 10 / SM 4.0

The performance of the 2600 XT is very close to that of the GeForce 8600 GT, but the 2600 XT has a performance edge when antialiasing is disabled. Although the GeForce seems to lead when antialiasing is turned on, it's not much of a real-world advantage, since neither card can effectively use 4x AA beyond 1024x768.
GeForce 8600 GT
Codename G84
Process 80 nm
Universal Shaders 32
Texture Units 16
ROPs 8
Memory Bus 128 bit
Core Speed MHz 540
Memory Speed MHz 700 (1400 effective)
DirectX / Shader Model DX 10 / SM 4.0

The 8600 GT was a terrible buy at $150, but now that it's under the $100 price point, it is much more attractive. The 8600 GT will slightly beat the old 7600 GT and X1650 XT in raw performance in the sub-$100 price category. In addition to speed, the 8600 GT has the added bonus of being DirectX 10 compatible, as well as being a good overclocker.

NOTE: Avoid the DDR2 versions of the 8600 GT! The GDDR3 versions are the recommended cards, DDR2 equipped 8600 GTs will be notably slower.
