estimated average
Processor bottleneck

The processor is holding this graphics card back at 1080p: the card could deliver about 44% more frames. A faster processor (or playing at a higher resolution) would make better use of it.

Best-value fix

No processor for this motherboard fully keeps up with this card at 1080p. The fastest one that fits, the Ryzen 7 9800X3D (about $704 new), gets you to about 198 fps. Playing at a higher resolution also uses more of the card.

What a bottleneck means

Every PC is limited by something. The processor sets a ceiling on how many frames it can prepare each second, and the graphics card sets a ceiling on how many it can draw. Whichever is lower decides your frame rate. A gap under 10% is nothing to worry about.

The graphics card setting the pace is normal and healthy, especially at 1440p and 4K: you’re getting everything you paid for from the card. A big processor bottleneck at the resolution you play is the one worth fixing, because part of your graphics card sits idle.
