They will ROI within 2.5 months as long as you ordered enough of them to beat the curve.
Someone needs to work on their math skills, if one ant is unprofitable then 1000 of them will be as well as long as the cost of running them /ant stays the same.
well it depends.
1 s-3 and 1 evga 1300 for your psu won't roi.
3 s-3's and 1 evga 1300 for psu might roi .
you did say as long as cost to run them does not change but maybe the poster was thinking like I just wrote
I am running 3 S3 (237.5 mhz) on a single EVGA1300 using PCI-e splitters on two machines (so each has 4 connectors).
What was your wattage on EVGA1300 per S3 when running at 250mhz. I wonder if I have enough power to bump all three to 250mhz.
