I've never understood what market wants a powerful CPU paired with a meddling and power crippled yet still expensive GPU though, except in a laptop where it's all you got. Pretty much every benchmark shows that if you want gaming performance, put almost all your money in the graphics card. I mean the high end processor is $366, you can get a $64 Intel G3260 and pair it with a $299 Radeon 290X for less that'll be a much, much better gaming machine though it'll use 200W more when you're playing.
Now if you really want that powerful CPU for non-gaming purposes that's fine, but then you can buy an i7-4790K and save the rest towards buying a real graphics card. I mean seriously, you're spending $300+ and the benchmarks are if you can play at 720p low quality between your number crunching? It does not compute. And it's a total waste if you decide that 720p is not enough, the integrated graphics will then be dead weight, which seems more likely to happen if 60-80% of your budget went to buying the CPU as opposed to buying an APU where you spent 60-80% on the GPU in the first place.
