You don't need a 6600k.
You can get an i5 6500 and h170 mobo for $250
Vs an 8350, aftermarket cooler, and motherboard for the same price!!
The cheapest h170 mobo is $90 and that cpu is $200 or at least in the USA.
8350 is $150 with a 970 board for $65 and then you can even add a hyper 212 and end up at $250.
EDIT: Not to mention if you really wanted to save you can get a Micro ATX board for the 8350 at $50
