Profitability has crashed hard across the board for everything and is still falling like a ROCK.  There isn't a safe haven at the moment in any of the alts.  Bitcoin is holding up so far, but that remains to be seen if it will continue.  Like others have stated investment in GPU's at the moment is questionable given the current risk/reward situation. 

There is the real possibility if things keep going this direction with pricing that there won't be anything that is profitable in a few weeks and people will start shutting down rigs.  If that happens you might be able to start picking up some GPU's for a discount as people start selling off rigs and the market will be flush with GPU's for sale.  Again you would have to gauge your willingness to take risk in a falling market.
