FayngOblivionageno it is not kuni i dont know where you got that information from. No game uses more than 4 cores dude and intel's cpus easily performs better in said games as well as benchmarks.
I watched a video actually comparing the 2 processors, and while streaming the AMD outperformed the intel, but all of the high quality pc gaming streams use intel, and everyone else recommeneds intel. Which would be better for games like Titanfall, CS:GO, and TF2?
Intel would definitely be better for tf2 and CS:GO, not sure about titanfall though it is still on the source engine. For the most part source games run on few cores (not utilizing say all 8 cores of an fx 8350) and favor intel.
For the 144hz monitor I personally would just say get cheaper ram and cut out the SSD or something to save up for the 144hz. Even getting a non-overclockable cpu and stock cooler IMO would be worth it, unless you absolutely need the top framerate on every game. 144hz is so much better than 60 :)
