[SOLVED] Will I get better gaming performance if I upgrade CPU?

Hey,

So I have a GTX 1080 with an i7-6700k. I was gaming on a 60hz 2580x1080 monitor. Not sure what my fps in most games were but they were playable. Planning an upgrade of several components but with industry and shipping delays, etc, I'm stuck waiting on parts. I've upgrade my monitor to a 160hz 3440x1440 and my fps at native resolution is in the 20's. I will be getting an RTX 3080 (when the model I want is finally released and there's stock). I'll also be moving to an AMD R9 5900X or 5950X.

The benchmarks I'm running using the windows Game Bar don't show me as being CPU or GPU bound, so something is obviously not reporting correctly. I know my CPU is a bottleneck for 1080p, but for higher res, it looks like it's a negligible bottleneck at 1440p and higher, according to https://pc-builds.com/calculator/.

I was hoping to get the CPU and GPU upgraded at the same time, to avoid having to dismantle my water loop for 2 separate upgrades, but with the RTX availability, I'm wondering if I'm going to see any meaningful fps boost at 3440x1440, with just the CPU upgrade for now. In case it affects the calculation, I'm also running 32gb of CL15 ram at 2133mhz, limited by CPU. When I swap to AMD, I won't be speed limited so it'll be 3200mhz

Thanks

The 5000 series sweet spot is rumored to be 4000MHz.
Yeah...but I've also seen it debunked as irrelevant even if true. Reason being a combination of the unified cache gets much less benefit from higher IF clocks (since the cores don't have to hit IF so often) and the big hit to latency as timings have to be relaxed severely above 3600-3733Mtps range.

Will be interesting to see

Yeah but I upgraded RAM only a few months ago. I'm not swapping it out for faster RAM at this stage. Just curious if upgrading CPU in November, will make any difference to gaming performance at 3440x1440, if I'm not upgrading GPU at the same time.
