I was wondering if I had to grab a better CPU because I can't run games (overwatch, GTA5, borderlands) at a constant 60FPS at 1080x1920 on ultra with my current i5-6500 and gtx1070.
Can you run them at 60fps or better with the graphics settings lowered to high or medium? If so then it sounds like a gpu issue though the 1070 shouldn't be struggling at 1080p. Have you installed the latest drivers for the gpu? Have you tried running something like msi afterburner to get a sense of cpu vs gpu usage to see which one is pegged at 100%?
If the cpu is at 100% and the gpu's only at 70% or so usage then a faster or better cpu may be needed.

Both that CPU and GPU shouldn't struggle at all on 1080p 60FPS in overwatch or GTA5. Check if drivers are installed and if the problem stays when lowering your video settings.
