    Hi Guys,
    why don't we start creating a list of the best (estimated at this stage) configurations divided in price brackets so we can help people like me who are thinking about getting into mining

    0 < x < 500usd
    mother board XXX with x*GPU YYY

    500usd < x 750usd
    mother board XXX with x*GPU YYY

    750usd < x < 1000usd
    mother board XXX with x*GPU YYY

    and so on, what do you guys think?

    Motherboard (with CPU) is not very important. Could be any cheap low end MB with enough PCIe slots. For this purpose I think you can easy use little bit old Asrock H61 Pro BTC. This MB have two extra Molex connectors for powering PCIe's, 1X 16x PCIe slot and 5X PCIe 1x slots. Of course if you intend to use more than one GPU you need riser(s) and (very impotant!) strong, quality and efficient power supply.
    More important is GPU and my opinion is that 2-3 AMD R9 Fury GPU's would be sweet mining rig. Of course rig should be open with enough air flow because heat disipation would be considarable.
    My idea how to begin build minig rig by importance:
    1. Power supply: 750 W or more (depend of number of GPU's), efficency at least 80-PLUS Gold
    2. GPU: one or more AMD R9 Fury or better
    3. MB and CPU: any cheap MB with Intel Pentium or i3 (or AMD) and enough PCIe slots
    4. RAM: 4GB, 1333MHz
    5. PCIe risers: PCIe 1x, USB 3.0, external Molex or SATA power connector (something like this)

    I opened a similar thread a couple of weeks ago without success. It's probably too early.

    Those molex on that board make no sense when using any serious GPU. Ignore them and use the powered risers that you have linked. The ones which use a USB 3.0 cable for data transfer because they are shielded and cheap, but have actually nothing to do with USB protocol. Never ever use ribbon cable risers, neither powered and even less so unpowered.

    You are absouletly right. But I like to be sure so I allways connect them. It's like a nun, she wishes to be sure so she allways put condom on the candle :D.
    Your remarks about USB cables in that case are also true. I like this risers because they are neat, reliable and working good. As you said, avoid ribbon cheap-shit at any cost.

    Could you use an old Zeus script miner?

    It's a brand new miners,so there aren't optimizaiton for gpu.
    It will be cool to check how differents gpu will perform on mining.

    These risers are just to move GPUs out or away from MB to facilitate larger boards in all slots and better cooling? GPU mining only requires a PCIe1x slot regardless of GPU being used?

    No unfortunately the algo is different; BLAKE-256 vs. Scrypt so ASICs will have to be developed from scratch, you will see FPGAs before that though. Any custom hardware that was made to mine Bitcoin or Litecoin will not work here.

    Exactly. You need to provide enough space between GPU's for better airflow. If you will acomodate more GPU's inside standard PC case there will be unsuficiet cooling because lack of airflow.
    PCIe 1x slot is enough for mining purposes. To be exact, mentioned risers are 1x on the side where it is connected to the motherboard. On the GPU's side is 16x connector with extra power supply Molex. Connection between them is standard A-A USB 3.0 cable. Please refer to link and you will find photo about this riser. And, of course very important, allways connect extra 6 or 8 pins PCI power supply connector(s) to the GPU. Failing to do so, you can fried mother board or GPU in case of 'extreme luck' :D you will fried both, best case is that GPU won't work.
    Best regards

    Your ROI is likely as good as anybody else that starts off with your current computer... the FPGA guys have experience this time around... I doubt it will take very long before you see FPGA's crunching away obsoleting any investment you've made. My guess, less than 2 months, if not released right from the beginning.

    Either way, I wouldn't consider investing in new hardware based on CPU/GPU processing, rather I would invest in something small like a raspberry PI, and an FPGA development board (all together less than $150). Then I suggest start learning what it takes to get that board running BLAKE-256 in massive parallel, which is exactly where my free time is going at the moment.

    To give you an idea of just how easy it is to get to this point:

    http://avnetexpress.avnet.com/store...MicroBoard.aspx&intcmp=EMA-BUY-AES-S6MB-LX9-G

    You can pick up an FPGA that you can plug into your computer for $89.

    Here is a link to a discussion from 2011... it only took a day to provide a proof of concept; https://bitcointalk.org/?topic=8543.0

    So to be honest with you, I wouldn't waste money on GPU's unless you really want to play games with a wicked graphics card.

    @Kyenos For what it's worth, the current GPUs smoke the current FPGAs in terms of GH/s. Certainly FPGAs use less power, but they also basically have zero resale versus a GPU which typically has a high resale value. I certainly wouldn't go the route you suggest...

    even very expensive ... I'm already quoting some.

    Only thing i can add here is think long term if you believe in this project & include cost of electricity in investment i.e. don't sell coins to cover it, just accumulate the coins & use them when services start accepting them or sell them on pumps & buy back on dumps.

    Öhh, is that Spartan-6s I see? They are kind of old by now, we used them to mine SHA256 in 2011 and 2012. There's 2-3 generations newer FPGAs on the market, with far better power / power consumption.

    I have a friend that designs FPGA and ASICs for plastic molding and manufacturer industry. I wonder what he uses these days.

    :)

    I agree their old and I agree that GPU's have a better resale value but... vHDL is the fist step to ASIC, which is the first step to out pacing even the most powerful commodity hardware.

    Personally, I'm more interested in the engineering than the resale of what I'm working with.

    Honestly, I think it's newer / better than my Spartan 6 but, I'm in it for the engineering so the end Hash/s count isn't my primary goal, that comes down the line.

    I'm a huge fan of the MicroBlaze chip that it supports, which should make drivers easy and I/O fast. Lastly, you get to use Vivado instead of ISE (which I've never used but hear great things about) so your really up to date with the direction XILINX is taking development boards.

    I'm very interested in your knowledge base on this... have you worked with FPGA's before? How would you rate your comfort level with this sort of development... nubi, expert, somewhere in between?

    Personally, I've got embedded exposure, worked with several small boards before but, always on the software engineering / application level... never at the hardware accelerated level. The closest I've gotten to the hardware is working with GPIO on the Stellaris launchpad:

    http://www.ti.com/tool/Ek-LM4F120XL

    But that's still 'C++' application / controller level (ADC, GPIO, Servos etc.) and no chance for logic gates etc.

    If you know more about this than me, I would love to pick your brain, if you don't I would love to collaborate?

    One week ago I did not know a thing about FPGA, but I learn fast. I am up for collaboration, of course.
    Please create an accout at xilinx and download Vivado ( 10 GB installer ). I think it can be used even without a license, but if not, I can share mine ARTY's one - it is site and device locked. Hope they will not go after us ;)
    Thinking price-wise it may be better to buy old bitcoin fpga miners.
