Why no love for probably the best mining GPU of all time, the Tahiti's (Radeon 7950/7970/280x) ?
I get like 600h/s with 1050/1650 @ 975mV ( about 125 watt from wall)
I used to mine LTC with these back in the day when they pulled like 350 Watt from the wall, each!
Much love for the Haiti here

Mine are on 900/1500 with 0.931v , doing around 500 each with claymore, with Srbminer i got lower results , what miner do you guys use for Tahitis ?
