4670k vs 4770k

[mbc07]

Wrong, both 4670k and 4770k have 4 cores, the 4770k however has Hyper Threading, which will have no impact in Dolphin at all, but may be useful for other applications, though. If you're aiming at Dolphin only, then save some money for anything else (like a GPU, maybe) and get the 4670k...
