yeah, it would be nice to see a conmparison between 7600GT and X850XT.
Maybe, but the X850XT is an SM2.0 part and I think that significantly undercuts its long term value.
The 7600 GT v X1800 GTO is a tough one. From looking at Firingsquad it seems to be a tight race.
7600 GT
Q4, Fear, Serious Sam 2
X1800 GTO
BF2, CoD2, B&W
As for less relevant games, they are pretty even in HL2, FC, D3, and Pacific Fighters at "playable" fps, but the 7600 GT takes Lock On and also does better once AA is turned on (e.g. D3, HL2, and FC). But the X1800 GTO is interestingly faster with AA in FEAR.
If price and features being equal, and performance the main equation, I would have to give a slight nod to the 7600GT based on the two sites I have looked at, but with the caveat being if you play BF2 the X1800GTO may be better. (e.g. the only PC game I play right now is BF2... but I am very excited for ET:QWs, so if this was my price range I would seriously look at the 7600 GT).
Will read some more reviews, but looks like my choice here is the 7600 GT.
