I'm not a hard-core gamer, honestly.
Denial!

Personally, I do like cranking all the graphics up just to the point where they impact performance enough for me to start moaning about it. I don't do OCing though because I know my luck, and my luck will be that I have the rare component that'll catch fire if I try.
As for regret, I could have the best price/performance combination that's ever been seen in the history of personal computing and I'd
still get a major case of "the grass is greener" in no time at all. Sigh. There's no pleasing some people; or at least there's no pleasing me.
