I7 2700K Vs 3820

Few days i posted sandy bridge vs ivy bridge i decided to go with the sandy. My problem is my local store do not sale 2600k's no more as i planned to get and i do not want an 2500k.

I will be using my computer for gaming, music production, and light to moderate graphics. Really not sure on over clocking honestly.

So now i cant decide between 2700k or 3820. I can get the 3820 for $220 while the 2700k is $280. Which should i choose?
