Yes I overclock I7-930 to 4.2Ghz. But I tend to buy a PC fairly high end at first then overtime increase the overclock. I would like to upgrade some of the maincomponants, ie Processor as things get cheaper, but INTEL keep changing the ruddy sockets... I went from Q6600 skt 775 standard at first purchase to in the end 3.2Ghz. My next move was having to change the entire barebone system. I should have gone AMD as at least they have the forthought to try and keep same sockets for ages. I have slight overclocks on GPUs but only software and light tweaks in crossfire, luckily most games have yet to catch up.
