I think people are blinded of asics, these chips and cards are cards that can be reused for other things, the fpga is an rather powerful one for that price.

If it's to expensive, one can consider if waiting forever for asics are expensive or not, atleast, with either fpga (that uses less power, etc) or gpu (that uses lot of power) should be used while playing the waiting game on asics.

Asics are there, but not readily available, for still some time..
