It really depends on what you want to use the computer for. If you will not be using the 4 extra threads that the 4930K will provide, than you would be wasting money. The 4930K beats the 4770K on paper, however in a real world situation, not a whole lot of applications can utilize that many threads.
i dont care about the money i just want the best cpu for OC and i see ivy bridge-e will be coming so what do you say guys ?
Its kinda pointless, it won't perform any better for gaming. As for OCing, the highest CPU for OCong is probably the FX-8350 frequency-wise, but it mostly depends on cooling. The IB-E will do both things fine, but no better then a much cheaper CPU. the IB-E is only for people who do heavy multitasking programs. For everyone else it is overkill
