I am currently looking to upgrade my gaming rig, preferably for 1440p gameplay. I am looking at a GTX 1070 as my main option for the graphics card. I typically play MMO's and Overwatch. I don't typically play AAA games like GTA or The Witcher. I currently have an i5-4570. Would I be better off upgrading my processor and getting a GTX 1070 or getting a GTX 1080 now and sticking with the 4570 until I can upgrade my processor next summer? Would a 1070 and an i5-6500 be sufficient for games like Guild Wars 2, Riders of Icarus, and Black Desert at 1440p or would I be better off with the 1080 and i5-4570?
