Just depends on how long the program continues. I've built quite a crunching setup. All these machines are running at home on my lan. I'm quite proud of the farm I've built up. I'll detail below for those interested:
P4 2.8C oced to 3.3
P43.2C in a Gateway all in one case. with LCD monitor.
P4 3.0 Gateway
P4 2.8 Gateway
HP Athlon 64 3000+ laptop (very fast)
HP Athlon 3000+ (pile of crap in my opinion!)
HP Athlon 2800
HP Athlon 2800
HP Athlon 2400
P4 1.6
PIII 1000
PIII 1000
PIII 750 Dell (soon to be 1000) when I get around to put the chip in lol
Celeron 366 oc'ed to 550
Via C4 1.2(800 mhz) another pile of crap!
Stuff yet to get online mostly for lack of time:
P4 3.0 (still in the build process, who knows maybe someday I'll actually finish it lol)
2 PIII 1000's (133 mhz)
2 PIII 966's (133 mhz)
PIII 1000 (100 mhz)
PIII 850 (100 mhz)
3 BP6's all have 366's that will do 550 np
Just wanted to crow a little.
