New build has changed the resolution I can run

I have just upgraded my system and it seems to be running nicely.
Gone from my old 4770k to a 3700x with 32gb 4100 MHz ram. Xmp seems to have worked.
I have also recently just got a 1440p 160hz monitor and on my previous system I could see definite slow down when trying to run F1 2020 at 1440p. Now I seem to be able to play it fine since installing the new build even though the GPU is the same rx480 8gb.
It surprised me as I thought it was the GPU holding back in the previous build.
Have the new components taken enough strain off the GPU to enable me to now play this even if it is a fairly low FPS?

Absolutely, your build before was being bottlenecked by your CPU.

You can use online bottleneck checkers to confirm this. Some even tell you what fps you can expect in certain games

It would depend on the game, some will respond really positively, other games won't. The difference between 2400 and 4100 RAM can be pretty significant for FPS too.

I didn't realise that the CPU was bottlenecking that card. 1440p did work in assassin's creed unity and civ 6. I thought i7's going back that far would be ok as they had 8 threads to play with and IPC was still pretty good up until Ryzen came along a few years ago as intel didn't move it on much until that point either as they had no competition.

Also I didn't realise ram would make a lot of difference. Ok it's DDR 4 over DDR 3 but in some comparisons between lower speed 4 and higher clocked 4 didn't make hardly any difference. That was only 1 review I saw though.
