Yeah I can't see why not. I wouldn't expect any great frame rates though. Might be a case of running it with out AA/AF. Might be worth downloading the demo first and see how that runs before buying it.
Oh wow, our specs are exactly the same except I have a 7600gt. Frankly, multiplayer will suck except at 800by 600 with lowest settings (unless you LIKE being killed or something). Single player I crank it almost all the way up though . If you want some more fps in multiplayer, I can help make you a config .
yeah i've learned that the transfer from a single core to a dual core is monumental with CoD4, the game lags like hell without one but with one its one of the smoothest playing games i've ever had.
like people already said, you shouldnt have a problem running it. (but yea, if you want to play over the internet, you'd have to play at lower settings to keep the framerate up,.. else you'll just be dead most of the time in multiplayer )
Well I have a 7600GS and I get about 40-50 FPS average (it fluctuates between 30 and 70 or so) in multiplayer at 1360x768, with everything on Low. I use Kobaj's custom config and it really helps out a ton.
