Okay so I'm hearing from some people that 64 bit is the OS of the future, so I decided to try it out. So I downloaded the 64 bit version of W7, bought a new hard drive just for this, installed it, and it runs just as good as the 32 bit version. Not much difference except my sound card drivers won't install because Windows 64 Bit insists on having signed drivers. The drivers for the 32 bit version work just fine. Adobe Audition 3 seems to be working although I have no sound. So here we go again with driver problems. So at this time I'll be going back to W7 32 bit version and use the new hard drive for back up/storage, or future experiments with the W7 64 bit OS. So now I know.
