Wouldn't hurt. I'm getting pretty good performance out of a 6000+, and I've playe dit on 4000+/4200+ and its wasnt as good by far. I can still get some lag every so often now with the 6000+ (w/ 8800GT SSC , 59FPS solid.) The Minimum is 2.8 GHz or faster (XP) or 3.2 GHz or faster (Vista), so a better CPU, again, probably wouldn help.
9600GTs SLI'd should be doing much better, so somethings up. Darn game is so resource intensive, I don't even think the minimums are close to being enough.
Peace, Penewah!
