in case people are curious i did some cpu and gpu testing with nvidia and ati etc
i found that mining Vertcoin was close to 3x more profitable than mining Darkcoin.
So if you wanted darkcoins then mine VTC and buy them

also i think VTC is more honest.. Dark coin is a rip off of Quark and they won't give any credit to Quark at all and play dumb about it.
they also have all kinds of trickery involved from day one like parading it around as a cpu only coin and not posting gpu miner links on the ANN page description.
Even though there was gpu miners around since day 1 ! so they have exploited the rep of being a cpu only coin to get people involved.. scammy !
Screw Darkcoin and their scammy bullshit.. their title boasts claims they can't back up too.. it's also listed on the CPU only coin listing topic.
