Im talking total power draw measured using a kill-a-watt. You figure in the ineffeciency of the PSU, HDD, and the mobo, you will see around 50 watts.
No, the processor draws 13W for the one I have and 10W for the next generation. If you compare that to the ztex FPGA 8W it's really ok.
The peripherals will draw on any other card too.
And the linux you get on any non x86 architecture has NO software support.
The choice is easy!
