I have the GTX 970 and i have noticed people with the same card has been capable of playing games on higher settings than me with better fps like the wither 3 wild hunt. i have noticed that everyone who plays it on higher than me has a better cpu and i was wondering having a quad-core 3.20GHz (intel core i5-4460) how much would getting something like a 4790K - http://amzn.to/1NADUdr improve my pc in terms of gaming?
