After about an hour of trying to fix my Vista 32bit installation (it wouldn't boot up), I decided to forget about it, and delete the Bootcamp partition. So now I'm interested in Windows 7 RC. I have an early 2009 iMac with 4gigs of RAM. Is it better to install the 64bit? I won't be doing much on the OS other than some casual gaming (Battlefield Heroes, and Street Fighter 4 when it comes out).
