***EDIT***
Also it appears as if some official releases are heading our way, these are 158.18 Vista 32bit and 64bit

I would also like to state that early testing shows us that Vista x64 STILL has bugs with SLI and machines using 4Gb of RAM, anyone with this setup and a 7xxx SLI card(s) will not be able to use SLI correctly unless they disable memory remapping in the motherboard BIOS in which case available memory drops from 4Gb to ~2.5Gb
