Currently I run an i5-4690k and gtx 970 with a 1080p monitor (I understand 1080 ti is for 4k). Question is as the title states and I'm worried about future proofing and possibly setting up for 4k res, on top of just upgrading the build since its running poorly on games I play with ugly frame drops (cant plat PUBG, ds3 frame drops sometimes, for honor, shadow of mordor, etc.). Any suggestions or even tips to boost my current build are appreciated, sorry if I respond late and thank you in advanced if I personally forget to do so!
