What are the other benefits of overclocking besides performance gains? For example, does it seriously reduce the lifespan or just increase heat output? What should beginners pay attention to and what are the basic rules? Do you think it's a reasonable strategy for someone on a tight budget, or is it worth the money and effort? What should those considering trying it know?
Is overclocking really necessary or is it risky?

I've tried overclocking on several old graphics cards and monitors around here (mostly for retro games), and the truth is that the balance between risk and reward really depends on what you're looking for. In my case, with a GTX 1060 I used to emulate PS1 and PSP classics, I increased the frequency by +10%, but the temperature would skyrocket if I didn't improve the thermal paste. Once I changed the paste and adjusted the voltage, the FPS gain was noticeable (from 30 to almost 60 in some titles), but after a year of use, the GPU started showing artifacts if I didn’t lower the settings.
The thing is, it's not just about heat: if you go too far with the voltage, the chip degrades faster, almost as much as if you constantly overheat it without control.
For those on a tight budget, I see it as viable if:
1. You have a good cooling system (a decent cooler or even water cooling in the case of CPUs).
2. You don’t mind sacrificing a bit of lifespan for more performance (especially on already obsolete hardware).
3. You start with mild overclocks and test how the system responds during long sessions. I used MSI Afterburner to monitor temperatures and voltages, and whenever the FPS didn’t improve enough, I stopped increasing them. If you have a motherboard with a good VRM (like B550 or higher), the risk goes down, but with cheap components, it’s a shot in the dark. The key is not to get obsessed and back off if you notice the system becoming unstable.
