I think i'll go with the 600w one. what kind of CPU should I get so I won't be bottle necking the card?
As long as you stay with the AMD Platform, I don't know if that will be entirely possible using the GTX 1070. Your best chance will be with the FX-8350/8370. Those are the top two CPUs that board supports. But your FX-8320 can be OC'ed to match their specs. And if you have a good one, even higher.
Get the card if you want it that bad and see what it does as to CPU usage vs GPU usage. Then you'll have an idea if you have a bottleneck problem or not.
