Some people prefer to trade off stability for a slight performance improvement. With modern hardware I don't think it's worth it to be honest. I want my computer to work day in and day out even if it means a 2% lower score in some benchmark.

There are also a lot of cases where you can overclock without sacrificing stability. The standard clock speed for any line of processors is simply the minimum it is tested for. But you sometimes get lucky and can get a better chip with more viable transistors. So you can boost the clock ok those and reap the benefits without any drawbacks. There are sites and services that do "binning" where they test the specific chips and you can buy ones that have been vetted to clock higher.

  And undervolting lets a CPU/GPU boost to higher frequency for longer before hitting power/temperature limits or just use less power to hit the same performance. There's a decent chance that any given chip can be undervolted enough to make a notable difference before becoming unstable.

  XMP profiles are another example where you can boost RAM speeds without much risk of instability [1]. I assume the manufacturer is just doing binning on their end and selling the higher performing RAM at higher prices. And the performance differences can be significant: 20% or more in certain workloads.

Yeah personally I’d rather build a PC with efficient power supply and quiet, high performance cooling. No gaudy LEDs either, just a plain case. I want it to be very stable and reliable and unobtrusive.

Some people prefer to trade off stability for a slight performance improvement. In my PC, I've got a Intel Core i5-3570K (3.4ghz stock) overclocked to 4.5ghz or something silly like that. I used the motherboard manufacturer's "one touch overclocking" feature to determine that speed years ago and haven't touched it since. The performance improvement is more than slight. Stability is rock solid across thousands of hours of gaming. I'm not running advanced cooling. $60 Corsair closed loop cooler and three Noctua case fans. System runs cool and quiet, fans throttle up and down nicely. Near silent when idle and still rather quiet under load. That is a pretty decent gain in performance for zero drawbacks and essentially zero effort.

  That's around the last generation when it was worth to overclock things, because the headroom on a typical consumer-grade -K cpu was at least 25%. Personally, I run a 4670K at 4Ghz, and it's been rock stable as my main machine for the last 8.5 years. It's finally beginning to show its age in 22-23, but the longevity and use I got out of a $200 processor is incredible. But when CPUs auto-turbo to 5+ Ghz, I agree, overclocking sort of loses its luster.

And with the energy crisis, power consumption is another consideration these days, particularly for a computer that is running all the time.
