Wow those look really tempting now. Pretty close to a 5970 / 6990 but without the power, heat, or noise. But as was said, they're only *just* slightly more efficient for MH/$.
I'm not sure slightly is the right word here...... BFL Single 813Mh/80w = 10Mh/1w At BEST, a 5970 can MAYBE to 5Mh/1w when it is underclocked / undervolted. So if you consider DOUBLE the Mh/w to be slightly, then maybe I'm dumber than I have been thinking. Ultimately what this means is, a BFL single will be profitable a lot longer when the next significant downward event happens in price or subsidy. Sorry Giga, I think I was focusing on price moreso than efficiency. Obviously your #s are right and no a 5970 wouldn't be anywhere near close. I was wondering to myself though if FPGAs can still be used for anything else except mining. I know the market will continue but if it were to crash, I'd believe GPUs to have some resale value vs FPGAs which I don't know what else you could do with. FPGAs are good for people who have high power costs, not great areas to mine with cooling, and perhaps a lack of space though. 4 of them would edge out the price of one (full w/case) rig + 3 5970s pretty well (let's estimate 3,200 MH VS 2,200 MH) by quite a good margin, though 3 FPGAs and you're kind of close there. I would again just wonder what else they could be used for before turning my entire operation into FPGA blocks. Actually with the price of 5970's at a little over 400 dollars right now + MB/CPU/Memory + PSU you are looking at an investment of about 1700 bucks (for 3 5970's). 3 of these are 1800 bucks... pretty close comparo if you ask me I'm not sure if I'm correct or not, but according to https://en.bitcoin.it/wiki/Mining_hardware_comparison, for 5970 to operate at 800MH/s, each would take 340+ watts, totaling 1320W (for GPUs) + 20 Watts (For the supporting PC) + Inefficiency of the PSU, that's something around 1400Watt (+/- 10%). Three of BitFORCE consumes 240Watt (less if powered from a high-efficiency PSU which has 3 outputs @ 12V). The extra 1000 Watts in the GPU solution, would cost: 144 USD per month in France (19 Cents per kWh) 266 USD per month in Germany (36 Cents per kWh) 66 USD per month in Russia (9 Cets per kWh) 155 USD per month in UK (26 Cents per kWh) 74 USD per month in USA (Average, differs from state to state) 200 USD per month in Sweden (27 Cents per kWh) Furthermore, GPUs need maintenance, may encounter fan failure, generate noise and heat. Please let me know if I'm missing anything. Regards,

gigavps, can you post statistics from some well-known pool? Your screenshots worth nothing.

Bullshit ! GPUMAX just works like every other pool ! Stupid nonsense...

Well, extra 1000 W in Ukraine would cost only $33 per month (0,37 UAH = 0,046 USD per kWh). In this case the possibility of a subsequent sale of the GPU in Ukraine (even used ones) for a price exceeding the price of new ones in the U.S. causing my preference to GPU-based solutions. However, this announcement of the FPGA-solutions are really able to make me interested in.

@BFL-Engineer: what is the efficiency of the PSU bundled with the Singles? I'm trying to get a feel for whether it makes economic sense for an end-user to look at replacing it with something more efficient. Also, do you have a specific 12V multiple-output supply that you could recommend?

gigavps, I had in mind that screenshots worth nothing because they can't prove anything. Turbor, do not shout at me. You are also in my potential scammers list now. Good luck.

lzsaver, if you read the entire OP, you will see that I provide video and photos, one of which is an screen cap of cgminer. This was required to collect the bounty. If this is not evidence enough for you, please ignore this thread and certainly don't purchase a single. More for me i guess!

BFL told me that their initial production run of Rig Boxes is already sold out..! Now this is really getting interesting...

Freakin AWESOME Now I can get to ordering mine How hard was it to setup the mining software?? I use Win7 & GUIminer for my GPU's,is it similar?? Any way to see the software being setup live?? I'm not a software guru BTW Does the power adapter come with it or did you have to order it seperatly from them?? Thanks gigavps You probably got excited & missed my post Can you enlighten me?? Thanks gigavps

Turbor, do not shout at me. You are also in my potential scammers list now. Good luck. it's best you stay away from BFL products. And don't say something is worth nothing just because you have no idea. Now keep mining at deepbit with your GPUs

Ok,I keep getting: Pool 0 slow/down or URL or credentials invalid I'm mining on deepbit,where is the "url" I need All I find is BBcode or setup for momchills,diablo,ufasoft or phoenix miners God,I'm slow to learn I'm planning on getting a few BFL rigs & really need to learn this Sorry for going off topic P.S. I got it going,was using login instead of "worker" ID,
