I currently have a 2400+ xp and I believe my FSB is 266mhz. I have 1gig of pc2700 ram and my video card is a geforce 5600ultra. I'm trying to determine where the biggest bottleneck is in my system for gaming. I'd like to get 2 or 3 more months out of this system before I build an entirely new one, but I can pick up a 3000+ xp for a pretty reasonable price and would like some opinions on what kind of improvement if any I might get in my framerates.
