Hmm... I run a GeForce 4, and have no problems with the 52.16 drivers, myself. I get 3dMarks comparable to systems quite a bit more powerful than mine. Actually, it's been many many months since I've had anything resembling an unstable WHQL driver from nVidia. Just goes to show, though, you never can tell. It's a lot of variables that go into making a modern Windows box. Some of it comes with skill and experience, and some of it comes with luck.
