ok guys, so basiclly i just got done buying all the parts for my gaming pc that ive been planning on building, but while i was on here asking questions about my powersupply i posted the specs of my system and someone told me that my cpu would bottleneck my system because i have a high end gpu and ram but apparently low end proccesor. the problem here is i just spent all my money on this stuff so right now im just going to stick to the build but i will want to eventually upgrade.so when i upgrade from a Amd athlon x4 740 to a Amd fx 6300 im also going to have to upgrade to another motherboard becuse the one i have has a fm2 socket and i will need a fm3 socket. anyway heres the question, when i install windows 7 os, does it install on the motherboard or the harddrive? in other words say i install windows 7 on my current system (which im going to) if i in the future decide to opgrade to a better mother board and proccesor, will i have to buy a whole new copy of windows 7 and reinstall it? thanks ahead of time for any help or guidance given, much appreciated. by the way incase your wondering heres my build
