First we have NVIDIA releasing a new set of Detonator drivers, now up to version 40.72, these are WHQL certified and claim they will bring some performance increase (dated Nov 11th).

Next in line, Tech-Critic is hosting a "Doom 3 Alpha Multi Fix", for those who got to your hands onto the Doom III leak (I finally downloaded it yesterday ;)), this patch is supposed to improve your performance somewhat.

Last, we have SiSoftware's Sandra 2003 that was released a couple of days ago. I already got my copy and seems the same as before, just updated support for new processor features, etc, that sort of stuff, worth a look actually if you benchmark.
