hi.so today my new components arrived and i'm troubled because i read various articles about what to do when changing cpu and mobo.the thing is that the new cpu is amd fx 8320 and the old one was intel 2 quad 8300.so i don't realy know what to do before installing the new harware,in the articles that i have read they say that since i have windows 7 i don't need to do anything.is it true?also i don't have the windows 7 cd because i installed this os 3-4 years ago and i have no idea where the cd is
