Is AMD Athlon x3 455 @ 3.3Ghz better than Core 2 Duo e7400 @ 2.8 Ghz for Dolphin?

Well, I can say that I've only played the single player, and not much else, as I've been avoiding anything that will slow it further. I'll be able to give you more information once I've put in my new power supply and GPU.
