I checked the i7 4790 and the rx 580 in a bottleneck caculator, it said 0.3% bottleneckHello so you aren't gonna like this answer there will always be a bottleneck in your system no system can be perfect what you can do is minimize the bottleneck I am unsure about the CPU as I am more familiar with modern CPUs BUT you should be fine since some run 2500s/2500Ks with SLI RTX 2080s
The CPU is running on 100% and the GPU 50%-60%, games stutter alot even on lowMy friend was running a i5 4590 with an gtx 1060 he upgraded to a 1070(which makes no sense as he has a 1080p 60hz panel)You should still be fine with that cpu but if you can get the 4790 for a killer price then it's well worth it in my opinion
The bottleneck calculators are never accurate and IMO shouldn't be used.I checked the i7 4790 and the rx 580 in a bottleneck caculator, it said 0.3% bottleneck
On my current CPU it's 22%
You're bottlenecking because you're running on 720p.The CPU is running on 100% and the GPU 50%-60%, games stutter alot even on low
Im playing on 720p 60hz
