But what will you do in the summer when the big guns come out? ;-) amd are planning heavy miner gpus. What do you think nvidia is going for with such low power overheads for such a low price :-)
Likely spending the rest of my mini-MAX coin "fortune" lol. Already building 2 6*7950 rigs and just researching what I'd like to do with an Nvidia rig. The new Maxwells are tempting with a ~90 break even and low initial cost.
Also, I doubt AMD has something lined up unless it is very specific to the mining market separate from their GPUs. The R9 290X is already based on their new architecture Hawaii and is very power hungry and hot, so they'll need another approach before they release more, lol.
AMD has of course a card lined up against the 750Ti, the R7-265. How effective it will be, remains to be seen.
I actually stopped by here due to this article:
http://www.forbes.com/sites/jasonevangelho/2014/02/20/nvidia-is-about-to-steal-the-cryptocurrency-mining-crown-from-amd/It has a blurb about the r7-265 comparison, similar hashrate 150 watts for the r7-265 and 60 watts for the 750TI.
Anyway I wanted to hear some other's input, thinking of order 6 right now from New Egg to build a test rig, but want to confirm the math. Supposedly 280 kHash slightly OC at 60 watts, heck even a 6 card rig would only need a 500 watt PS, would be saving all around if true.
You can easily get these cards over 300kh with max GPU OC (+135) and a +200 or better memory OC.
Has anyone measure the increased wattage draw when overclocking? That seems to be the main benefit, if they go up too much past 60 watts I think.
I am going to buy one just for testing, but would be interested in any other experiences and what the best setup for a 6 card rig would be. For sure a reasonably priced MB with 5 or more slots would be nice, as mentioned the ASRock 6 slot BTC one always seems sold out. Also I think a 600 watt PS would be plenty? I see Corsair ones on sale from time to time under 50 bucks. Thinking if you build supporting infrastructure for under $200 (MB, CPU, PS, USB Stick) ,might be a viable rig.
Also, anyone have a BAMT type image with Cudaminer going yet? To make these work I would think a USB based boot image would be best>
So far you can't adjust the TDP past 100%. So I would say 60w is the max draw but I haven't measured it.
