Definitely worth it. I can't remember the last time I ran a computer without an overclock. My CPUs always get overclocked on day one and stay there (e.g., my 5930K has been at 4.5 GHz daily use since day one. I don't even know what its performance is like at the default clocks). My graphics cards from NVidia have always been overclocked and remained there since I experienced noticeable gains in every scenario. From AMD was a mixed bag. Also with AMD almost always the overclock needed to be reduced by a few MHz after 3-6 months of use. For my current setup, I have not overclocked my graphics cards more than 1405 MHz (that is +25 on the core) since my card is on air. For benching/gaming the 1506/8200 are stable clocks but I don't feel comfortable having my card on air run at 80C temperatures. So once I put it in a loop it will also remain overclocked.
In the past, even on air cooling my NVidia cards have always remained overclocked (e.g., 970 SLi, 680 SLi, 670 SLi etc.). The gains, especially in SLi are noticeable allowing me to sometimes either up a resolution or add more AA.
- CPU overclock is a must. If you aren't doing it, something is wrong with you.
- GPU overclock on NVidia yields noticeable results. AMD cards are a hit or miss in my experience.
