I've built a gaming PC with an Intel i5 10600k processor, an RTX 3070 GPU, and 16GB of DDR4 2666 MHz RAM. Based on various online benchmarks, my setup should easily hit over 120 fps in games like PUBG. However, I'm seeing fps in the range of 80-120, no matter what graphics settings I use. The fps seems to drop particularly when I'm aiming at players. A tool I talked to suggested it might be a CPU bottleneck, but those benchmarks indicate everything should be fine. Interestingly, my friend, who has a similar setup with an i5 10400f and a GTX 1660 Super, is also experiencing similar fps drops. What could be causing this?

Your friend's setup being similar to yours but with a lower tier GPU is pretty telling. The i5 10600k and 10400f are nearly identical in terms of performance, so if you’re both getting the same fps, it does hint at a possible CPU bottleneck in your case. Just remember that those online tests often run in ideal conditions, meaning background tasks are usually disabled, which isn't the case when we're gaming.
Make sure to enable XMP or EXPO in your BIOS settings. If your RAM isn't running at its full speed, it could definitely affect your performance, especially in online games. However, you mentioned that 2666 MHz is the max for your RAM. Even so, it's best to verify that it's running optimally.
It sounds like you should check your GPU usage while gaming. If it's only about 30-40%, that might indicate that something else is limiting your performance. You mentioned having an H410 motherboard with not-so-great VRMs, which could be impacting your CPU's ability to maintain stable performance. Plus, the 4.4 GHz limit might not be the main culprit, but it's worth exploring if it's affecting your performance when under load.
