Sure you have the mobo and other stuff to add to the price, but then again that GPU based rig is more flexible in that it can mine other alogs, including new ones that may come out. Also, as others have pointed out, the GPU rig can be parted out and resold if need be, whereas the ASIC is just a paperweight.
I used to think this way.....until Bitmain started going after the 2 main algos that gpu's mine with.
I wouldnt be surprised if equihash is next...nothing is asic proof.
And no ASIC is fork proof. Hard Forks are the nightmares of Shitmain. Just fork. If they create another ASIC, fork again. They'll give up eventually trust me. Nobody can be
retarded.
