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

[PaRaDoX_94]

I just overclock my athlon @ 3.552 Ghz and it works great in most games with openGL, exept the metroid prime saga and mario kart wii, those runs @ 60-25fps depending on the area, ssbm and ssbb at full speed, and the zelda games (WW, TP & SW) runs perfectly... how much performance will the i5 give me in those games, if most of them run fine or playable?
