I've decided to dip into my savings and just get a new computer as mine seems to have too many problems that aren't even worth fixing.

Just wondering, seeing as I'll most likely go with Vista, if it's worth getting 64-bit? I'm not sure what compatibility is like compared to 32-bit. I am mainly running programs like Maya 2008, 3DS Max 2008, Adobe CS3 packages, Final Fantasy XI and newer games (which I know will work, as they require DX10).

Also, what's OEM mean? If I buy an OEM version, does it mean I can format my computer and re-install it? Or can it only be used once?

By the way, no one in here saying "lawlz go xp" or "lawlz linux"!
