I got a 7600gt KO. I could play the SP demo on (close to) medium at a 1024 x 768 res.. The frames were in the 20-30 region, they would drop below that when anything happened though. SO low would probably be attainable, rest of your specs willing.
I'd advise you to just get COD4. The graphics are killer, and the game doesn't need $1000+ worth of GFX just to play it maxed smoothly. I played the demo on this card and it looked and played great at respectable settings.
crysis works fine on 7600Gt ive got one, i play on medium lowish, cant exactly remember my settings on the demo. but works alrights on medium low d/l demo and try b4 u go buy crysis
Yes, a 7600GT can play Crysis at most in medium, I own one, and I could play it ad medium at about 20 fps, but thats because my CPU is old and not OC so maybe you can do better!
