This question might of been asked before, but nvidia has released a lot of new drivers since summer. There are also similar topics on Laptopvideo2go but that was the 8600M GT in general and not MBPs. In addition, Nvidia says the newer 180.XX drivers don't support the 8600M GT but they work just fine. (XP Pro SP3). In my case the 180.43 have worked the best for a while,but i'm having a fair bit of trouble with them now. I got 4414 points with 3dmark06 (default demo). So: Which drivers work gave you the best performance/stability? Post 3dmarks if you can.
