Just use compatability mode within vista.
For the record ive used vista 64 ultimate for a few months now and its never once BSOD' or crashed. Everything works with it, including command and conquer red alert 2 and mediaval, total war 1 and 2. As well as all my apps.
My spec:
e5200 @ 3.8ghz
Tuniq tower 120
Gigabyte DS3 P45
4gb OCZ ReaperX 6400 @ 1200mhz
8800GTX (downgraded from 260gtx and dont see any lack of performance)
everything else yadda yadda
I do alot of folding@home so nvidia cards ftw.
BTW Stu, how much you want for your 8800GT ?
