Like I said, I wouldn't get the 5820k. I would get the 6800k if I get a 6 core.The 6700k is built more towards games, with the 5820k being more for modeling. For $50 more, the 5820k has 2 more cores, and hyperthreading, so basically 4 more cores.
I don't know. Newegg is having a black friday sale.What's the max you want to spend on a graphics card?
