Ive been searching for a while and I cant find a decent answer so I figured I would ask here. I want to change out the processor on my desktop, but its a typical mass produced HP and from what I have been able to find, the processor is soldered to the motherboard. So, that means I need a new motherboard and it also gives me an excuse to swap out 32 bit Vista for Windows 7 64 bit.

So my question is, can I just get the motherboard I want and swap it in, or will it cause all types of problems? I really dont want to build a new computer from scratch, but the computer is about 2 years old and is having a little trouble with MW2 and BFBC2.
