Why people get APU's for dedicated CPU's is beyond me. It "might" is all I can say. Get an FX 6300 at least and I will upgrade answer to "you sure can" prob on medium settings"
his rig can run it just fine on med-high settings depending on what server (if he plays multiplayer) that he chooses. As for the APU comment, the new line that AMD just released can play BF4 on MEDIUM settings at around 30fps and that's without a standalone card, JUST the apu.
and, for the why get that for a dedicated, alot of websites offer FM2+mobo deals a hellava-lot cheaper than a am3+mobo, and he has the added security that if his vid card fails, he can just use the onboard.
