Okay wait, when you said "I'm downgrading" earlier, did you actually mean that instead of buying an i7 you were going to instead buy the 8320? Because that's not what downgrading means, as that implies you already own the i7 and plan on replacing it with a new motherboard and processor.
If you're building a new computer from nothing and you only do very light gaming and general web browsing, just buy a core i3 or an amd apu.
