I'm considering upgrading my graphics card to an RX 6600, but I currently have an i3-9100F. I'm worried the processor might limit the GPU enough to make the upgrade disappointing. Is this a reasonably balanced pairing, and what's the best way to check whether my CPU or GPU is holding back performance?

Use an in-game overlay such as MSI Afterburner to monitor CPU and GPU usage while playing. If the GPU is near 95–100% usage, it is usually the limiting component. If the GPU usage stays low while one or more CPU cores are maxed out, the processor is likely holding things back. Also compare frame rates and frame-time consistency instead of relying only on usage percentages.
There’s no need to be afraid of a bottleneck. Install the RX 6600, see how your games perform, and then check whether you’re satisfied. A bottleneck just means one component is limiting the other in a particular game or setting; it doesn’t mean the hardware is unusable.
Rather than chasing a perfect CPU-to-GPU pairing, focus on the performance you want. The RX 6600 is a sensible upgrade even if your processor cannot unlock its full potential in every game. You may see the biggest gains at higher resolutions or more demanding graphics settings.
The RX 6600 should still improve gaming performance, but the i3-9100F is only four cores without hyper-threading, so it may limit the card in newer or CPU-heavy games. You can use it for now and plan a CPU and platform upgrade later. A used Ryzen 5 3600 or Ryzen 5 5600 with a compatible motherboard would provide a much stronger six-core, twelve-thread setup.
