My wife is loves to play ark, and I enjoy upgrading or tinkering with PC's. We're tight on money, but with black Friday approaching, and Christmas, I'm trying to help upgrade her pc. She's currently using a pre-built, with an i5-7400, 16gb ram (highest speed I could use with her mobo), 1060 3gb graphics card. I just bought her a new cpu cooler and ssd, but I'm trying to figure out if upgrading the cpu will help as much as upgrading the gpu to either a 1660 or 570/580. She has two 1080p 60 mhz monitors with freesync. Should I upgrade the cpu? What are your opinions on the gpu?
