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.
