I built a PC with a Ryzen 5 5600XT and recently found a great deal on an RX 9070 XT, so I decided to upgrade the graphics card. I know the CPU may limit the GPU in some situations, but how noticeable will that be at 1440p?
I mainly play demanding AAA games such as Expedition 33 and Resident Evil 9, rather than high-refresh competitive games like Counter-Strike 2. My system has a B550 motherboard, 16GB of DDR4-3000 CL16 memory, a 750W Gold power supply, a 1TB SSD, and a 1440p 180Hz monitor. The CPU is currently cooled by the included AMD Stealth cooler.

Assuming you mean the Ryzen 5 5600XT, I wouldn’t worry too much. At 1440p, especially in demanding AAA games, the RX 9070 XT will usually be doing most of the work. The exact balance depends on the game and settings, though—some CPU-heavy games may limit your frame rate before the GPU reaches full usage.
The 5600XT is only slightly faster than the 5600X, so advice for the 5600X applies pretty much unchanged. You can always move to an X3D chip later if you want higher minimums or better performance in CPU-heavy titles.
The included AMD Stealth cooler should prevent dangerous temperatures, but a basic tower cooler could help the processor maintain higher boost clocks and run quieter. I’d also consider moving to 32GB of RAM eventually. Sixteen gigabytes is still usable, but newer AAA games can benefit from the extra capacity, especially with background applications open.
A similar setup with a Ryzen 7 3800X and an RX 9070 XT can handle 1440p and even 4K without obvious problems in most games. That suggests your 5600XT should be perfectly usable for now. I wouldn’t replace the CPU just because of the word “bottleneck”; upgrade when testing shows that it’s actually preventing the performance you want.
Install the card and check real usage rather than trying to predict a single bottleneck percentage. If the GPU stays near 100% usage, you’re GPU-limited, which is ideal. If GPU usage frequently drops while one or more CPU cores are maxed out, the CPU is holding things back.
It varies by game, resolution, graphics settings, and target frame rate. At 1440p in visually demanding games, the limitation should generally be reasonable, while CPU-heavy games or very high refresh-rate settings may expose it more.

Yes, I meant the 5600XT. It’s a little faster than the 5600X, but not by a huge amount. I’ll probably consider a CPU upgrade later if I run into limits.
