Graphic card help ? Options

[NaderG]

i know it is a car website but maybe someone here can help me out !

I want to buy a card and i came down to chose between two :
GeForce 7950GT 512MB 256-bit GDDR3 : this card has 256 bit memory interface , DDR 3 memory and 512 memory , with like 24 pixel shader , the only bad this is that it is a DX9. 160$

GeForce 8600GT 512MB 128-bit GDDR3: this card is almost the same specs , but it is only 128 bit interface , which means it delivers the same power SLOWER than the other one BUT it is a DX10 card. 130$

both cards basically have same core clock speeds.

p.s:my tech level is ok so i might be wrong and i dont like ATI
if anybody have any suggestion of a better card that cost less than 160$ , that would be great

The x600 (X is generation 6,7,8x00) series is always the 'budget' version. A 7950 GT wil outperform a 8600 in any game. The only thing going with the 8600 GT is its support of DX10. But if you think about it, the card itself is to weak/underpowered to even take any advantage's (nicer textures, animations etc, etc) of the DX10 features in games. AND you have to use Vista for DX10. Something no one would consider. Vista sucks, XP pro is alot faster. according to OfficeBench/Mark tools.
