You are the last person to tell that no gpu miner for nist5 exist.
Gpu miners exist, but most of the new coins you see today doesn't support mining with the JSON-RPC html protocol (getwork()) in the wallet. This meens that without a pool, you cannot use ccminer or sgminer to solo-mine. I linked 2 new coins and asked for pools, and it turned out that they had pools already.
Here is my original mesage.
