nVidia is working on the new 6900 series, which will significantly drop the price of the 6800 series. Also the 6850Ultra will be available with a core clock of 550 and Mem clock of 1.3Ghz. Nothing compared to the possible clocks of the 6900Ultra (600/1.6Ghz!!)
IF you wait until the beginning of Feb, you will be glad you did. The 6900 Series will take full advantage of the PCI Express bus as well. New texture engine as well. This new texture engine should be able to render over 64 textures per pass! Hmmm, let's see if they pull it off!>!
BTW, I think if the 3D1 could be dual SLi setup, you are looking at scores breaking 30,000 on 3DMark03!!!
