As the title says i'm doing an all AMD, Corsair, and MSI build, im using an MSI A88XM Gaming motherboard its an FM2+ socket and I'm planning on a single R9 290X. What CPU should I pair with this an A10-7850K or an Athlon X4 860K. would either of these bottleneck this GPU, and would they perform any different since the Athlon is just a normal AMD APU without the graphics cores?
