I've been searching for these cards specs on Darkcoin but its been so long since i've mined Darkcoin (it was a hot summer) but now my desktop is back in action ready to mine.  Can someone help me out?

I'm using my SGMiner from May: sgminer -o stratum+tcp://stratum.simpledrk.com:3353 -u Address -p x -w 128 -I 13 -k darkcoin


Is there a better more targeted approach?  Is there a more effecient miner out now?
