It´s good to increase the hash power but if everybody can increase it then is pointless and you will only increase power consumption .. so please hvc.1g stop updating the cgminer!
You maybe speak out the truth!
My happiness after increasing my hashpower has gone.

Its better than some other guys squeezes AMD cards with new cgminer in secrecy. And at least we can fuck back all those 750ti noobs

Just for note - hashrate incrase is +30% but power consumtion rised just by tiny 4%, so no big deal, here are results for my rig of 4* R9 280x at 1100 / 1500 (various brands, no voltage / BIOS optimalization at all):
cgminer v5 - 61MHs / 850W
cgminer v6 - 80MHs / 880W
