Re: X800Xl or X800PRO ?
i thin you mean PCI-EX, also XFX are very cheap manufacturers and i wouldnt get that brand...go BFG or something around that, LEadtek or MSi are also good. the X800XL, but i would go with the 6800gt PCI-Express card, because they easily play doom 3 and easily o/c to ultra speeds which saves u lots of money.
