Hey all so i recently ugpraded my gpu from a 750 to a 5500 xt and upgraded to 16gb of ram. However my cpu usage is still quite high on certain games especially lost ark the 1 i upgraded my pc for. So, i want to over clock my i-5 4670k. I know this is difficult but i heard that it can increase performance by a lot. Any suggestions and help would be appreciated what program should i use and any general tips would be nice.
