What is the best ATI graphics card out there running PCI-E 16x? I'm not sure what brand name is the best, asus, saphire, etc. And is the X850 worth it instead of the X800? Thanks!

Check my system. I can say only that I'm highly satisfied. 40fps locked in 95% of situations.

Thanks for the response. I picked up a Visiontek X850 XT and am building an AMD 64 FX-55, epox ep-9npa ultra mobo, 1gb crucial ddr pc4000, 680w power supply, and using the 200 gb wd hard drive, basic cd rom, and sb audigy platinum from my old machine that died on me after a power surge. Anyway, for the price I threw out, I'm hoping to get 40 FPS on this baby, especially since I fly only in the VC and 100% traffic
