Hmm, I'm surprised no FPGA board designer has bought this. This should hash really well!

Its a monster FPGA no matter what you use it for but the thing about mining with it is someone would have to write a bitstream for it - which would require a skilled programmer and a lot of work

But at this price you could probably bash out a slow inefficient bitstream that isn't optimized, and still have some major bang for your buck. ;D Then tune it later.

So this is how BFL got the magic flowing ???

Why such a big price difference ...

That's not the same chip as BFL, I'm fairly certain.

this has 250k logic cells - which is a bit more than the spartan-6 chips in icarus and x6500 that you can get 200mhash from but it would probably not be able to do 800mhash - probably more like somewhere in between
