The x850 xt Pe is the best single card solution. it can beat an 6800 ultra in all games at the highest resolutions with max AA and FSAA. The only game where nvidia has an edge is doom 3 in which the 6800 ultra does around 10 fps better.
If your only concerned with fs2004, then get this card. It will beat a single AND a dual 6800 ultra config.
I have this card in all but 2 of my computers. This card is the best single card solution out there. There is no better card.
So, why is your overkill pc (in your sig) powered by a 6800Ultra then?
