I'm looking to upgrade my rig, specifically my GPU. I'm want to replace my GTX 970 with a 2070, the thing is, I'm not sure of my I5 4670 non-k CPU will bottleneck the said GPU. I'm on a rather limited budget, so I want to see if I could get away with not buying a new CPU, though if needs must, i'll just have to bear with it. Any help is greatly appreciated.
Rig specs:
i5 4670
GTX 970
samsung 1tb ssd
16gb ram
