My experience show the opposite opinion. I don't have 280, but I have 7950 and 290x. I don't bother attaching KillAWatt meter to 750Ti -- just feel the temperature and you know it is not burning. No external fans, no noise, I am super happy so far, even I did not make ROI so far on 750Tis -- I haven't made ROI on any cards yet, but mining itself is fun.
The 280x's will be in the range of 32-40C as well at these volts mining energy efficient algos. They dont make much more noise but I really dont care about that as I am not mining in bedrooms.
0.756v? that's below the minimum in idle for 280x series, i don't think you can get them so low , unless the core is also around 300, which make the mining pointless
Yeah also the stock volt is 1.25v for some cards - That doesnt mean they wont work lower. I had my MSI 280x's on 0.756v for quite some time when profitability was really lousy - They will do around 800Mhz, draw about 70W mining something like dark coin and still give more performance than a 750Ti. Obviously they are more expensive also but I am just saying that the 280x is a very versatile card.
Does anyone know how many Mhashes will a 780Ti give at JPC ? been craving for pair of these for ages, maybe its the right time
