ok cheers for your help. i'll look at the amd's on overclockers. if i just changed my gpu to, say, a 6800 for now (and upgraded cpu etc in a few weeks) would i get any better performance or would my cpu etc just bottleneck it? cheers, nick :)
As long as your existing celeron isn't too underpowered, then a 6800 will make a big differance.
Don't kid yourself its all down to your CPU and RAM, its NOT!
Your 3D card is where I'd be spending money.
