Out of the two cpus you listed I would take the FX8320, but you'll need to add a decent cpu cooler like the $29 Cooler Master 212 Evo to really get your money's worth out of it. If you're willing to spend close to $250, I really recommend the i5-4570.
I ended up getting the AMD. And with that, how necessary is the cpu cooling for single monitor gaming at 1080i? I rather pay the 30 than fry my build but at the same time it would be easier to buy one later.
