If going with 6800k I would get 2133mhz ram, the apu is proven to perform better with faster ram in games.
Personally I would buy the $100 pentium combo from microcenter if you can get it. It would allow you to buy a cheap video card now that would outperform the 6800k, and be set for the latest Intel processor due out this summer or anything Intel has made in the last 1+ year. You can also get 1600mhz ram and save their too.
I ran a 6800k last winter, it was "ok" but any emulation or real gaming will be extremely bottlenecked by the lack of per core performance. I went to a 4670k afterwards and it was an eye opening difference. I have since downgraded to the pentium g3258 because I wanted to save some cash and do mostly emulation.
