Windows 7 in MBP? (Noob-Question)

[I-Eat-Flowers]

I'll buy my first mac as soon as they are updated and I am planning to install Windows 7 on it additionally to OSX. I can get win7 for free from my university thanks to the msdn academic alliance program.

My only problem is that there are two different versions of windows 7:
"Windows 7 Professional (x64)" and "Windows 7 Professional (x86)"

Which one of them is the right on to use it on an MBP? This might actually be a really stupid question but I just don't know that much about computers.

Would be great if someone could tell me which one I should get and also give a brief explanation what those numbers stand for. Is that the size of the machine's adress bus in bits?


thanks

x64 stands for 64 bit, and x86 stands for 32 bit (x86 is the CPU architecture Intel and AMD use for their mainstream CPUs and which is used by Windows and Mac OS X and Linux and other OSs, x64 is also based on x86, it's just 64 bit).

For more than enough threads about those two versions:

x64 = 64-bit
x86 = 32-bit, I think

Get the x64 as it can support +3GB of RAM

EDIT: Damn you're always faster than me spinnerlys!

32 bit and 64 bit are the instruction size. And by the way install 64 bit.
