OK, some of you may know that I've delayed my intended upgrade to AMD64 over christmas. I really want to upgrade, but have no £££ at the moment so now I'm going to gamble on OCing my current system. The situation is - general use of the PC isn't a problem, I can do things without waiting for the apps to load. The main problem is in gaming - not that I have a lot of time to waste, but I would like the games to run a wee bit smoother - 9-39fps in CS is just not acceptable in anyone's opinion. So, my question is - Do I OC the CPU+GFX card, or just the GFX card? I have tried OCing the GFX card before by about 25-75MHz but it didn't show any improvement over the 39fps that I was getting out of the game. Besides that, I think the card kept overheating because frequent system crashes occured. Any suggestions?
