I'm building a new PC specifically for living room/TV gaming, and I have a buddy who is helping me assemble it and he's all into overclocking and tinkering with voltage and all that. I'm a little hesitant as lots of what I've read says overclocking is less about performance and more about the fun of playing with settings and getting more out of the chips. I just want this to run nice for games and not have to worry about special heatsinks or anything or having to tweak settings every few weeks.
So have any of you done much playing around with overclocking on your gaming PCs? If so, have you seen much improvement, or was it more for the fun of doing it?
I'll be using Quad Core i5 3450 3.1 GHz.
Video card is Asus Radeon 7870.
