Hi guys, I am blowing the dust off of an old 2600k, chucking a water loop on it and trying to OC it. What I want to know is what is the best GPU I can get before it stars to be throttled by the 2600k? Currently just have a couple of 580 GTX's lying around. I am really looking for a card that'll run 1080p at the highest settings possible, even on newer titles. I am looking at a RX 580 or seeing if i can get my hands on a Vega 56 (is this overkill?)? Most 1070's are a bit beyond the budget for this build. edit: Really only looking at 60-75 fps for games like Destiny 2, DOOM, GTA V, Overwatch, HotS.
