Well it happened! GPU miner is now out for HVC.
Just switched over all my 280x rigs from LTC to HVC.
Getting 85MHash on 1gh pool with 16 280x cards. The awesome part is they are drawing less than 1/2 the power than the cards were drawing mining LTC. And temps are at a cool 40-45 C.
Running the new CGMiner... switch was crazy easy. LTC difficulty has gotten so high. I'm making 2x profit now at current low exchange rate. This is all great - because people will jump to HVC, which will adjust LTC difficulty back down.
HVC price already gaining mass volume on MintPal.com. Today is going to be very VERY exciting!!!
