I have a EVGA 8800 640OC I went to EVGA web site to look for the latest drivers. They listed a 158.45 dated May 29 07 and it was not a WHQL signed driver, so I looked at Nvidia site and found there 8800 driver 158.24 dated June 1 07 and was an WHQL signed driver. So the question is; which one if any, would one use. With VISTA, unsigned can give headaches, as I understand.:-)

Generally, with Vista x64, unsigned drivers are a headache, though Vista 32 is no party in the video driver department. I'm using the 158.24 release with an MSI 8800GTS 640MB and have no issues at all. I tried the 158.45's which are listed as beta and really saw no issues but when the WHQL drivers came out, I installed them just to see how they performed.One of these days AMD/ATI and nVidia are going to release a set of drivers that work as expected. At the moment, neither company has a strong Vista driver. You're expected to fiddle with them to get any satisfaction :-) Regards,Jim KarnNOTHING is foolproof to a sufficiently talented fool.

Thanks for your input Jim; this has been sort of a pain in the you know where, when you have a new OS and FS, and a new comp all at the same time, along with being some what software illiterate. However as before, it will all get worked and we will find the sweet spot, and life will be good again! ;-)
