Before you buy your video card, be sure to do a quick google search for "<video card> neverwinter nights issue." I got a GTX480 awhile back, and I really wish I had done that search first, since there were some issues with cloaks and framerate. It's gotten better in driver updates, but NWN still runs with a lower framerate than games that have come out well after it. The only issue I have with windows 7 is with alt-tabbing, but that might just be a general nwn issue or something else altogether.
