I have 3 running 1 stting and 1 in the process of being built for a friend, only work on it when a hot deal comes up guess I am lacking compared to some people, if you go to my best friends house he has 6-7 all running but will not run seti because he keeps most of them shut off to save power I have 2 machines running now that average bewteen them 2ghz, a 1900+ and a 2100+ overclocked.
