You must decide what is more important for you. If gaming is more important, 3570k. If multithreading much, 3770k but i don't think 3570k is much slower in that either.
Edit: and if you won't overclock, you can even do with a 3470. If there is "k" at the end, it means the CPU is unlocked and can be overclocked. If you want future proofing though, you can get away with a 3570k and overclock it. And intel chips are good at heat and energy efficiency. You can overclock your 3570k and reach higher level of speed while keeping it still cool. If you are thinking about overclocking, you are advised to get an aftermarket cooler along with that CPU

and then overclock the transistors (geek joke) out of it.
that means i have, kickass single threaded performance and multithreading power to match.
next year i get kickass single threaded performance and multithreading power to match but then overclocked = good. *fibre-optic high five*
this way i get the best of both worlds. like semi-skimmed milk, only completely different.
