BFG GeForce 8800GTX OC2 768MB SLI HDCP Enabled Dual DVI PCI Express (626MHz Core Clock) (2000MHz Memory Clock) (1450MHz Shader Clock) or Sapphire ATI Radeon HD 3870 X2 1GB GDDR3 TV-Out/Dual DVI/HDMI PCI-Express - Memory Clock 1800MHz Core Clock 825MHz
the ati card will perform better (keep in mind it is running 2 gpus) than the GTX. The ultra is the only single gpu that can beat the 3870X2 straight up right now...at least until the 9xxx series flagship cards launch. If you can get the X2 for less, then do it. It really is a good card. Don't get me wrong, the GTX is awsome, but in higher end stuff....it is beginning to show its age. Look at this chart:
note that the 3870 comes in forth? Well, that is the single gpu version. The X2 would be right around 1-2 on the list. You decision should be based on the price point right now. You might even consider waiting a few weeks to see if the 8xxx series drops in price.
