I'm very happy with the performance of the 6800 GT on my home system. Not happy with bugs in Nvidia's drivers*, but hey, you can't win them all.

*= The latest one, in their latest drivers, is that the video overlay gamma control is scrod. Your DVD playback is all screwed up and can only be set to 3x gamma or 0.50 gamma, nothing in between. Even if you never touched the gamma before, it's all messed up the first time you try to play a video file or DVD. You have to go into the control panel select "Advanced Mode" for the gamma control to work, and at that point it's set properly by default. SIGH.

This happened when I tried to watch the final Doctor Who. Turn it on and all the colors are screwed up. Fortunately I figured out the work-around within 5 minutes when I recognized the problem I was seeing on the screen.
