Out of curiosity, how well do these FPGA boards hold their value?
Beats me, but I would think their ability to retain value would be pegged according to the value/difficulty of bitcoins since they'd have little to no use for people besides mining?
With Radeon GPUs, you can sell it to someone for mining or to someone who intends to use it for gaming making it easier to sell and hold value.
Exactly what my thoughts...
Paying $400 for a GPU is a much smaller investment than an FPGA, if you can easily sell it for $300 later...
...even with painful electricity prices.
