I'm using the 8.17.11.9562 drivers on my eVGA 8800GT OC and W7 Pro w/64bit and no problems. PC was put together on 11/20/2009 and the 8800GT came from an older and earlier build I had running XP Pro. I don't normally update GPU drivers unless I have problems. If it isn't broke, don't fix it, is my motto. Some may argue that you miss out on new and better gaming by going this route but I disagree.
