I've recently decided to take the plunge and replace my elderly XFX Geforce FX5200 with a PNY Geforce 6600GT which I will be taking delivery of tommorow. I was just wondering if anyone could give my any idea of how much better games will perform (plus base spec is P4 2.4GHz N/Wood 800MHz FSB, 1025MB DDR400 (4*256) dual channel)
