Yeah, I would think the OS itself would be plenty stable. Generally drivers cause the stability problems.
I agree. I had a few threads about my problems when I recently upgrade my mame cab pc from a P4 to a core2duo. As you can see, just running a 64bit compiled copy of mame gives you a speed boost in most cases.
The problems I had were drivers related. For some things like my wifi card, they don't have vista x64 drivers. Then, when I ripped out the and stuck a wireless bridge outside the nic, i found that SailorSat's Soft15khz didn't work with Vista x64. :-( I expect that as time goes by, i'll start having problems getting XP x64 drivers.
