OK so now what....
2 last 2 cards are being shipped back to Amazon due to failing fans. I have either the opportunity to sell the rig and get out of the business of mining or I have to buy new GPU. I only have a case (HAF-XB) not a large multi-card rig and it seems if I use anything but buying 4 750ti cards I run in the red losing $0.50 per day, not much granted but still a loss. I could look at either a couple of Sapphire R9 280x Vapor-x TRI-x cards which will run at about 360k/hs with a system 550w ish draw. Or buy 4 750ti's that I might get 560k/hs out of with a system power draw of 300w ish, but the has rate is less, should I care? its more efficient, but are the cards useful enough if I stop mining. my Pc has a 6870 AMD card in it as it is, where as the Vapor-x would definitely be an improvement should I decide to stop mining and keep a card.
I'm almost tempted to give up as there is virtually no profit to be had, or should I go with the 750ti's for efficiency sake or a couple of Vapor-x's as the better hash rate will serve me well if the prices go up

Good question, Did you factor in that with 2 280x's you should get around 720 kHs? It sounds like you factored in the power, but not the increase in hash... I'm planning to move my rig in with a friend back at te dorm because electricity is killing me (only about 10-15 cents at the moment after paying for power). Your call, my first suggestion would be to make a friend (we're going to split the profit for a win/win).
Yeah I was using coinwarz and ised 720 hashrate at system power of 550W or 4 x 750ti at about 140 hash per card = 560kh/s with about a 295W. the 280x cards only turn a profit if a card goes up in price. the 750tis make $0.10-$0.50 a day. It just doesn't seem worth it right now
I could go with the 280x cards on the basis they are better cards with a better resale value, though thats all speculative of course.
