Benchmarking?

[CocoPops]

Interested to see how my PC performs against others, plus looking to see where I could gain performance.
So what should I be looking at running to benchmark it? Not run anything for years, used to be 3dmark iirc?

Looking for bottlenecks etc?

I mean, there shouldn't be any... but checking would be a good place to start?
i7-13700KF/5090FE/64GB RAM/2TB SSD Should be top notch right? But I have been getting some stutters recently in games.
