In the Topic it says "ATI Fire GL X2 256MB or a 6800 ultra whats better?", but the link you gave us was for a "PNY Quadro FX 3000 256MB DDR2". Did you mean to do that, or do you want advice on the 6800 ultra and the Quadro FX 3000?
The 6800 Ultra and Fire GL are two completely different cards. The 6800 is made for gaming. The Fire GL, although the specs may look good on paper is not going to be outstanding for gaming because the Fire GL is more of a "professional" card. Professional meaning you have a business and u need to make a presentation and use multiple monitors and have very good resolution. For gaming I'd definitly go with the 6800 Ultra. PNY makes good cards so you could try them.
