Its probably not, the problem is that the X800 Pro plain sucks ass. There is no other way to put it. If I had to rate the card, I would give it a 1/2 star out of 5. Getting it is the worst hardware mistake I have ever made, aside from buying an HP before I built this PC.
The X800 Pro may be good when comparing it to like a GeForce 4 MX or a GeForce 2, but when comparing it to the 6800GT or even the $200 6600 GT, its just so weak and lame.
