I sold my i7 3770k + R290 for $650. I decided to upgrade for free and pocket the change.
Currently running at 3.8 ghz 1.3volts 1.1 SOC on the stock cooler until the Gammax 400 comes. I have 2 of them on R7 1700X and the chips stay cool at 3.8 ghz 24/7 (max 60's). The XFX 390X DD will do 1150 core and 6200 memory at +50v and +50 Power
This will play any game at 1080P max settings while streaming easily.
