I've been debating first whether the fx-6300 would be enough to play games likes Crysis 3, Farcry and BF4 on Ultra setting with a r9 280x getting 40+ fps. Now I heard that this Cpu would be bottle necking this card. So would it be better to upgrade that cpu to the FX-8350 or switch out for an Intel board with a i5-4670k. Would it be worth upgrading the AMD cpu and save a couple bucks or settle the damage by going with the Intel CPU. I want this PC to be primarily towards performance. willing to sacrifice a few dollars if it means I get better fps, IF IT IS SIGNIFICANT!
