So I have a Haswell system running 4570, 1070Ti, 16GB, Mag24C 144Hz monitor. I play The Division, 100% load on CPU but only 40-50% on GPU getting 80 to120 FPS on lowest settings. So I am thinking I should be able to reach 144 FPS and a little eye candy turned on if I get more threads or faster clock speeds or do I need both? Don't want to spend more than I have to. I am on a budget. So I gather I am bottlenecked by my CPU. How do I answer the question of what will solve my problem? Best case scenario is that an i7 4790K would do it - or do I need to go current gen?
