Lets all be serious.... Unless you're doing intensive 3D modeling or massive 4k gaming a 6600k would be completely fine. I have mine OC'd to 4.7 GHz at 1.35v. Idle it runs about 28-30c depending on how hot it is outside (currently at 37c with 3 tabs open and running battlefield on my other monitor) . I have the lower end H60 Corsair cpu cooler on it so it isn't like I'm fancy. Just drop $220 on the 6600k and be happy with your purchase.
Edit: it's OC'd to 4.8 @1.31
