I'm currently using a 165 Hz 1080p monitor with a GT 1030, Intel i3-10105F, and 24 GB of DDR4 RAM. I'm considering upgrading to an RX 6600 mainly for competitive games such as Rainbow Six Siege, Fortnite, and CS2. I'll use the lowest settings, except for Fortnite's render distance. Do you think this upgrade will let me take full advantage of the monitor, or will the CPU hold me back? Online benchmarks seem outdated because many of them use much stronger processors. I'm currently averaging around 40 FPS and would be happy to reach at least 144 FPS.

The RX 6600 is roughly several times faster than a GT 1030, so you should see a massive improvement. However, the exact frame rate depends heavily on the game and settings, and your i3-10105F may become the limiting factor once the GPU is upgraded. Reaching 144 FPS is realistic in some competitive titles, but maintaining 165 FPS everywhere is not guaranteed.
A four-core, eight-thread processor like the 10105F may hold back the RX 6600 in CPU-heavy situations, but it should still be a substantial improvement over the GT 1030. For Siege, 144 FPS should be a reasonable target at competitive settings, although a precise estimate depends on the map, resolution scaling, and whether you’re aiming for average or minimum FPS.
The RX 6600 is a good upgrade, but benchmarks using a stronger CPU may not match your results. At low settings, the GPU has less work to do, so the processor becomes more important. Fortnite in particular can become CPU-limited, while Siege and CS2 should generally run very well, though dips below 165 FPS are still possible in busy scenes.
I’d mainly be satisfied with a consistent 144 FPS. I’m not specifically trying to reach 240 FPS, since that would likely require a larger platform and monitor upgrade.

That’s the kind of estimate I was looking for. I mainly want to know whether the upgrade can get me close to using my 165 Hz display in Siege and the other games.
