I've also meant to ask.. is there any issues with a 64-bit OS running standard 32-bit applications? You need to run 64-bit versions don't you?
Nope, runs all my 32 bit apps with ease. Only one i've had a problem with is VLC media wplayer which, when loaded, shuts off the aero graphics and makes them solid.
Sonar works amazingly in 32 bit and 64. I just installed 32 bit one and it seems plugins work a tiny bit better due to the lack of need for bit bridge...
