Quick overclock question

[RadioheadR6]

Hi all

I've recently built a new gaming pc - Intel 920, 6Gb RAM, and an XFX 4870x2

I've managed an overclock of 3.6Ghz on this so far...

Anyway, I set everything back to stock settings - everything runs fine, including games.

My question is whether it is necessary to overclock this? - It runs games fine (incredible quality), and I've not noticed any slowdown of the PC...

I don't do too much video encoding... The main reason for getting this was for gaming. I also like to fiddle with technology too, so playing around to see how fast it goes is of interest to me...

The point I was trying to make was that it seems unnecessary to overclock at this stage - When games are made that the PC will struggle to play, then maybe overclock it...?
