I have the funds (saved up 4 years, waiting for a game worthy of a good Rig), for a nVidia 7900GTX SLI setup. I googled and looked at tom's hardware, and I know the nVidia SLI probably performs the best. But, what's the % increase over the ATI X1900XTX (my fallback) on the game TES:IV Oblivion? That's the main game I'll be playing. Also, will the SLI cards be too hot? I'm not that worried, as a friend recommended the BFG Card's Lifetime Warranty, but the heat might damage other components. However, ATI's Crossfire looks promising. It outperformed nVidia's 7900 GTX when Oblivion was renamed to AFR-FriendlyD3D.exe. I don't know which one to get. OR just save a ton of money and get the ATI X1900XTX? Thanks for all your time.
