Congratulations ... that's the same card I've got! It serves exceptionally well for the most part. The only qualm I have is that I have a widescreen flatpanel monitor, and I also tend to play a lot of older games in which higher resolutions and widescreen aspect ratios are not options. Registry edits can fix the resolution issue, but aspect ratios are another matter. In other words, the video card and monitor stretches the image out to look all squashed and ooky, just to fit the display's native resolution.
Most modern video cards (including the 8800GT) have ways in which to preserve aspect ratio for older resolutions, but unfortunately, there's a major bug in nVidia's drivers, and that feature has been broken for going on two years now. If they'd fix that, I'd be 100% satisfied with it.
If that's not going to be an issue for you, I'd say that you're set.
