Well my buddy (xxbassplayerxx) said the 4770k can be bought for $280 and the 4670k for $200. He also said depending on the game I'll see 10-30% improvement, mainly due to the architecture. If that's the case then it seems it would be a reasonable upgrade. Especially since I hope to get ~$200 for my i7 950 and EVGA x58 tri-sli mobo. I'd probably go with the 4670k too since not many games utilize more than 4 cores/threads.
