i'm saying that it is possible. you're probably not going to improve performance as much on said board, and the system's older (and weaker) power supply will probably balk.So, are you saying, I CAN put a Geforce 6800 ultra in a P3B-F
the fx5200 is a pretty lackluster card, and i'm not so sure your i440bx chipset would let you successfully overclock said bus.Might it be better to get a PCI FX5200 and OC the heck out of the PCI bus?
