Greetings.
About the mining: As far as I know all you really need is a good GPU, that other stuff doesn't matter too much.
About the ASICs from BFL: Well it looks promising but the question is who sells a money printing machine? Either the company is making losses because they could have made more money with mining or the customer is making losses because by the time he gets the machine the difficulty is so high that it's pointless.
Completely true, but if you build out a Rig.
Say 4 GPU's AMD 7950 (1240), MB (170), 1600watt PSU (280), Processor (100), 4 PCI-e cable extenders (55), 32GB RAM (230), 128GB SSD (150), Simple built aluminum frame (50), OS w7 Pro 64 (140), Extra Cooling fans cpu + others (100)
Anything I'm missing? we're talking 2600 easy for a fully built out rig that will run what 2.5GH/s ?
