I am looking at moving over to 64bit Vista, Can anyone tell me if there is a big difference between Premium and Ultimate? I use my rig mainly for gaming. I also heard that there were problems with X-Fi sound cards. Can anyone tell me if they have been resolved? Especially the problem with using optical out to surround sound speakers? I really would appreciate any help given. Thanks.

. That or business..... but then I lose all the multimedia stuff.
