Currently running an i5-6600k@4Ghz and a gtx 1660ti. Im finding in more cpu intensive games such as overwatch,fortnite, warzone etc. im struggling to maintain 144fps and getting frame stuttering as my gpu is running at about 60-70% load with a 90-100% on the cpu. I play pretty much every game at lowest settings to max out my fps as I care more about a smooth experience.
Looking for any reccomendations for a cpu upgrade that would be worth it in terms of future performance over the next 2-3 years as well.
