I have a new 15" Macbook pro (2.53Ghz, 4GB RAM), and I was wondering which I should install as a guest OS in parallels - Windows 7 32 bit or 64bit for best performance?
with a core 2 and only 4gb ram I would go with 32 bit, but down load both betas and and compare them. i know 64 is the future but 32bit will run better with only 4gb ram.
