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
