Thanks for the great welcome! For Gamer, here is a short list of the systems I have crunching now:

1 AMD 64 X2 4800+
1 AMD Opteron 242 (two procs)
2 AMD XP 3000+
1 AMD MP 2800+ (two procs)

Also I have:

1 P4 3.0
1 P4 2.6
1 P4 2.2
1 P3 1.0
1 Xeon 2.8G (2 procs)

Systems get added and removed somewhat often as they tend to get re-tasked .

To answer another question, I only have concentrated on Seti and CPDN. I tossed in Einstein recently when seti was down and CPDN would have problems on the X2 4800 machine (I still don't run CPDN on that system because it causes it to freeze up for some reason)
