Seriously, the XC7V2000T is not a cost effective part for bitcoin mining. It's really targeted for ASIC emulation.
You don't say...

It would certainly not be for production use. You guys should really put out a trimmed down chip with just a crapload of LUTs/logic cells, maybe an ADC or two, and a couple PCIe lanes... like the K325 with more logic. I'm sure Xilinx knows its own market better, but the premium chips are are a bit too premium. Just sayin'...
