I say YES,
because mt.gox is offline the BTC is broken, butI think in a few weeks is going up again. So you need at the Moment 37 PTS for 1 BTC, Bitstamp take the lead I think.
I have 1x HD7870 2GB 1500 CPM and 1x R9 270X 4GB 1900 CPM. Tomorrow I get 2 Sapphire 280X makes ca. 7000 CPM, I jave Money to Invest so no Problem for me, but In Germany the electricity
is expensive. With 10000 CPM you make in 30 Days ca. 33 PTS. So its time to make a lot of PTS. When you have 1 Card, forget everything its Gold Rush. When you have a few Rigs and Money to invest you can make Profit. The Time of the BTC comes, in Berlin is the first Germanys BTC Cash Terminal. You can pay with BTC, but you cant MINE BTC.
Is there another good COIN? Dogecoin, Primecoin I dont know.....
PTS is great I think. Kind Regards from Germany
