This guy modifies ATI's driver releases into what they should be. I've used his drivers for the last 3 months or so and I've actually experienced fewer lockups at higher OCes with much better performance. Also has a bunch of modified Voodoo 3/4/5 drivers that should be good based on my experience with this guys work.
