It comes down to the game but it should be a good pairing for the most part.

Your performance issues is actually going to be due to the memory, 2400mhz is too slow for AMD Ryzen and will cause either lower FPS then 3200mhz or more frequent/drastic FPS dips.

When you increase the resolution you are less likely to have a cpu bottleneck as the gpu has to work a lot harder to render frames at higher resolutions so no the 3900x wont bottleneck a 1080ti at 1440p. In regards to the ram the Ryzen Infinity fabric architecture has a performance drop off under 3000mhz.
 
the 3900X is pretty darn respectable in any variety of gaming scenarios I saw it compared to , particularly against the 8700K/9700K at any resolution... (Frankly, the few hundred dollars less expensive 3700/3800 will do 98+% as well, as there is little scaling in gaming performance yet for above 8 cores/16 threads...)

Definitely don't purchase a 3800X. All the tests out there indicate that the extra cost for a 3800X doesn't provide any noticeable performance boost in real life. The 3700X is the best bang for the buck, and as mentioned earlier, you can put the extra savings towards better RAM. I am currently running with 3200 Corsair Vengeance RAM, and it is a pretty sweet setup.

Thanks so much for the feedback guys! I looked into the performance difference and it seems for gaming that the 3700x and 3800x aren’t much different. So I’ll probably just run with the 3700x as suggested. What raam would you guys recommend. I see I need above 3k MHz but I have been reading that some brands aren’t able to hit the advertised speeds. Really appreciate the replies!
