I would say the price sucks. Was looking at the MSI RX580 8 GB, I bought mine when they first came out for $220 shipped and now the same model is going for $499. Even the 4 GB versions are about 1.5x what I paid back then for the 8 GB version.
Crazy times, anyone who buys at these highly inflated prices is going to have a very hard time to ROI much less earn any profit. Heck, at $499 even if you get free electricity it will take nearly a year to break even and that's a big if as I am sure difficulty will raise well before then pushing the actual date out even further.
