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.
