      (I'm always amused and amazed when people think we're stupid.)

      Power consumption of the C2758, as used on the A1SRI-2758F, is 20W TDP.
      Power consumption of the C2558, as used on the A1SRi-2558F, is 15W TDP.

      http://ark.intel.com/products/77983/Intel-Atom-Processor-C2558-2M-Cache-2_40-GHz

      Just as a quick-n-dirty comparison, the  A1SRi-2558F motherboard is $360 on Amazon

      http://www.amazon.com/Supermicro-Mini-DDR3-Motherboards-MBD-A1SRi-2558F-O/dp/B00HS4NLHA

      The A1SRI-2758F is $340 on Amazon.  Yes, it's less.

      http://www.amazon.com/Supermicro-MiniITX-Retail-Motherboards-MBD-A1SRI-2758F-O/dp/B00FM4M7TQ/ref=sr_1_1?s=electronics&ie=UTF8&qid=1400397161&sr=1-1&keywords=A1SRi-2758F

      Since everything else in the box will be the same, let's you've spent $40 to save 5W.

      There are 8765 hours in a year, yielding a delta slightly less than 24.09 kWh used in a year.

      At the highest tier, Austin energy charges residential customers $0.11400 / kWh.  At this rate, you
      will save $2.74 per year, by spending at least $40 more to get half as many cores.

      Perhaps you don't live in Austin, but I did pick the highest residential rate (in Austin). 
      At that rate, (assumptions noted), assuming electricity rates do not change (more assumptions), and not
      counting interest or TVM, it will take you around 14.6 years to pay back.

      Of course, you live in Australia, not Austin.  Using this report from the Australian Energy Market Commission, the average market offer price for residential ("Household") consumption is between 24.49 and 24.67 c/kWh, but these are Australian 'cents', not US 'cents':
      http://www.aemc.gov.au/media/docs/2013-Residential-Electricity-Price-Trends-Final-Report-723596d1-fe66-43da-aeb6-1ee16770391e-0.PDF

      This changes the equation only slightly.  Making the (entirely unwarranted) assumption that you could purchase the Supermicro board(s) at US prices (and ignoring shipping / duties / etc.), I note that at today's exchange rate, 1.00 USD will buy 1.07 AUD.  Picking the 24.49 c/kWh, this equates to 0.23 USD / kWh.  This is within striking distance of "2X' the electricity rate, so you might well pay off the difference in price in half the time, or 7.3 years.

      While there is a 4-core board coming (shhh!, it's a secret), it is not the A1SRi-2558F.

      Edit:  noted that aus_guy is in Australia, not Austin.  Adjusted / added figures to reflect his situation, sorta.

        I haven't tested the C2758s yet but my typical recommendation has always been to go for an i3. There is not much of power saving difference or in other words you won't be a $100 richer after running an atom or other CPU slower than the i3.

        Assuming you pick a slow (1.7GHz), dual core, 'mobile' Haswell i3 such as:
        http://ark.intel.com/products/75107/Intel-Core-i3-4010U-Processor-3M-Cache-1_70-GHz?q=i3-4010U

        The TDP of the part is 15W, .vs 20W for the C2758.  You have 2 cores at 1.7GHz, instead of 8 at 2.4GHz.

        Assuming you pick a faster i3, such as the i3-4000M, TDP is 37 W, and you only have 2 cores, instead of 8.
        http://ark.intel.com/products/75104/Intel-Core-i3-4000M-Processor-3M-Cache-2_40-GHz

        Many people do not understand that though the C2000 series is named "Atom®", it is, in fact, very unlike the Atom CPUs you know.  This one, literally, "goes to 11".  In simple tests (such as compiling pfSense), it benchmarks a lot like an 8 core Xeon system from 2009, while consuming far less power.

          Sounds good, I look forward to some updated figures.
          I think everyone would agree that the current hardware sizing guidelines are looking pretty stale. I have suggested some manner of community generated database in the past but it never got much traction.

          Steve

          We're (finally) working on a documented testing method.  This would allow community-generated results to be submitted that could be compared.

            Great!  :)
            I look forward to submitting some numbers from my ancient hardware.  ;)

              Anyone know if there are any install/driver issues with 2.1.5 or 2.2 with the supermicro c2758 board?  I want to build one and just want to be sure of what work I may have to do to get it running.  Please share any info you're aware of.

              thanks!
              Jay.

                I just ordered a different 2758 board. The intel c2000 processors are oriented toward communications, and the c2*58 processors have QuickAssist. This is hardware acceleration for encryption and compression. These chips are designed to replace larger power hungry servers with smaller atoms in the router/vpn market.

                I'm a pfSense n00b but have almost 20 years with Linux. The Linux kernel just got support for quick-assist. Apps don't seem to have it yet.  I expect FreeBSD will be at approximately the same state.

                The board I ordered supports 64g ecc or non-ecc memory. Surely there's a reason why it supports twice as much as a mainstream i7. Obviously for mainstream uses the atom will be stomped by the i7, but the pfSense use case is exactly what c2*58 processors were designed to do.

There is not much of power saving difference or in other words you won't be a $100 richer after running an atom or other CPU slower than the i3. The processor itself slows down when not required and has the added juice to push snort, dansguardian with clamd, squid and other packages all at the same time.

                  Wot?

                  i3-4150 is 54W http://ark.intel.com/products/77486/Intel-Core-i3-4150-Processor-3M-Cache-3_50-GHz

                  C2758 is 20W http://ark.intel.com/products/77988/Intel-Atom-Processor-C2758-4M-Cache-2_40-GHz?q=c2758

                  Today, there is probably a slight performance advantage to the i3.  Tomorrow you're going to want the cores.

                  Trust me.  You are going to want more cores.

                    C2*58 doesn't mean QuickAssist.  See:  http://ark.intel.com/compare/77988,77986,77984,77983,77981,77979,81270,77978,77976,81328

                    The linux kernel got QAT support last Summer.  You will never guess who Intel has tapped to do the QAT driver for FreeBSD.

                    Have you priced 64GB of ECC ram?  :P

                      I haven't managed to find anyone selling 16GB SODIMMs yet…

                      I can break anything.

                        I also had trouble finding 16g sticks but since i need 2 sticks it was more than my target anyway. I got 2x 8g sticks for under USD $200. The non-ecc memory was about $4 a stick cheaper but I don't remember exactly what the memory went for that I bought.

                          Please help me decide on this.. C2558 Rangeley has 4 cores, and the C2758 has double up the cores up to 8.

                          Also, there is a huge price deference between the two.

                          C2758 Rangeley >> $299
                          C2558 Rangeley >> $235

                          Thanks..

                              VPN service, Proxy, etc. or I can run VMware esxi 6 using board, and install pfsense on the host and WAN port will be connected to my modem.

                                What does etc. really means? Squid, Snort, ClamAV, pfBlockerNG, SARG, SquidGuard and DPI on top?
                                It makes a huge difference.

                                or I can run VMware esxi 6 using board, and install pfsense on the host and WAN port will be connected to my modem.

                                Why, I would install pfSense natively on that board and then it will be enough for all your requirements.
                                For ~$65 more if you are able to get it sorted take and go with the C2758 one.
