dont know if i messed up or not but when i installed windows 7 on Vmware Fusion i use 63 bit. 2006 Mac Pro. has always ran really slow. is it because i installed a 64 bit instead of a 32 bit windows.
Bootcamp supports only 64bit, so if you go that route, you cannot use the 32bit. Vmware Fusion supports both, and there shouldn't be a huge performance penalty between the two. If you're incurring some performance issues, then its more likely caused by other factors.
