I was still running two q6600 in my household up until recently, I still have one in my own desktop mildly overclocked to 3.2 per core, As I don't game or do much other than a bit of photoshop and film encoding plus some internet and film watching the q6600 is still more than capable, I did fit a nice Samsung ssd to it last year to modern it up a bit though.
My wife's media centre used to have a q6600 but I fancied a tinker so did the 771 mod to it, Quite easy to do with a small file and a special sticker. It now has a xeon quad running at 3.6 per core but would probably clock much higher, I think I paid £15 or so for the xeon cpu, If more people realised how easy it is to run a 771 cpu in a 775 board I doubt they would be cheap on ebay any more.
Just to add I'm not a complete retro head when it comes to computers and I do have an ok lenovo i7 laptop but to be honest I've not warmed to it and it sits idle most of the time.
Deano, yup I'm a righty mate even though I'm right handed.
I was thinking about buying the black version but after seeing this is had to go for it. I've already got a few black face divers so thought this was a bit different.
