I run a Dual Inteal Xeon 2.8Ghz, With 3GB DDR Ram, and can turn out 4 WU's per hour, But i'm not going to, cause that is when i allow seti at full priority of both CPU's, so i cant do much else really.. I Gave up with the SETI business when i was on my T-Bird 1.4, 1gb ram, Was just taking too long....
