Hey all: Nvidia has just posted (well at least recently) new forceware (video) and nforce (chipset) drivers for my 7950 video card and 650 sli mobo. The chipset drivers have not been updated since January so this may help those with driver issues.
I have both packages installed and so far no issues. If you run Windows update it will report a new sata controller driver which is dated 7/2/2007. Not sure why it does this, but the driver appears to be the same.
FWIW, sandra benchmarks increased dramatically for my sata 2 seagate drive. Before it would benchmark out no better than a sata 1 drive. Now it holds it own against sata 2 benchmarks. Have not seen any real-world speed increases.
