My understanding is the AMD card does NOT require a driver, The Nvidia Gforce requires a driver to launch the startup screen but that doesn't prevent system booting. It puts the startup screen into firmware so it displays the SU screen at boot, before the OS has launched. I am told the AMD card has a different workaround for this.

Robert, do you have a cost for running MacPro v MacMini v iMac as £/hr?

Not thought of a small wind turbine to offset your bought electricity? One of the people that lives in the beach front properties at Snettisham has a turbine and he claims he doesn't use mains electric at all. With so much wind in the Wash (theres a massive commercial turbine collection off shore) it apparently works for him completely. You don't mention other domestic appliances ....fridge, freezer, washer. When we've been away on several weeks holidays in the caravan I was surprised how much electricity was still used....the only items left on while away were the fridge and freezer. In fairness we've now replaced the old freezer as its energy efficiency was off the scale...at the bottom.

To be honest I don't think it would be meaningful, other factors come into play. I tend to leave my computers running 24/7, the difference in computing power is like comparing the cost of running a Mini with the cost of running a Land Rover or a large limousine. We all know which would be cheaper to run, I grew up driving large powerful cars like the 3 litre Alvis, Land Rovers and my Rover 3500s but now drive a little Skoda diesel. Since I switched from using my (dream machine) 6 core MacPro 5.1 with 8 internal drives and two 24" monitors running night and day, to a 27" i5 4 core 14.2 at the beginning of July, my electric consumption has plummeted. Depending on your monitor I would think a Mac mini would have the same effect, the two monitors which I use with the MacPro, consume very little power compared with the power gobbled by the MacPro. I did metered them for a while but decided it was the MacPro which was the villain of the peace! The monitors were small fry. Here you can see the drastic reduction in the consumption of power. I was away for most of May and June but bought the iMac at the beginning of July. The router element in the lower graph also includes an LED lamp above my desk and various chargers for iPhone, MacBookPro and my iPad. September was a five week month and October is only three weeks old so far, so a downward trend seems to be suggested.  I think personal usage patterns will have a large effect on consumption, I often start at 6am and work at the computer on and off until 11pm ish. I have found the MacPro still consumes a significant amount of power over a week even when shut down, complete savings can only be achieved by switching off at the wall socket or pulling the plug. During Aug to Oct, I have scarcely used the MacPro, it was shut down but still plugged into the electric. This week I have now used the MacPro for three full days, I will be interested to see the figures on Sunday when I take the readings. In fact I am writing this with the MacPro! I am looking forward to seeing the figures for November and December by which time the numbers should have stabilised and a broader view can be seen. For browsing the internet, writing eMails and partaking in forums, the iMac is just fine. Even a bit of spreadsheet use or simple image editing but when dealing with large numbers of large images, terabytes of music files, other processor intensive and storage intensive tasks the Mac Pro is a clear winner with at least eight (maybe nine) internal bays available for hard drives including up to three very high speed PCIe slots for SSDs, which make the biggest improvement to performance per buck I have ever seen. The sheer convenience of being able to slide hard drives into the computer or even run very fast external drives on eSATA or Firewire means that for me at least the MacPro is an indispensable tool and manageable cost wise by employing the iMac(s) for low demand tasks. So that's my take on the computer side, for now.

Wind is difficult and expensive to harness, the turbines are expensive to maintain and not 100% reliable, the rapid changes in delivery rate (gusts and lulls) and the nature of the power demands a more complex conversion and storage mechanism. Not to mention noise and planning permission issues. Solar, while admittedly not 24 hr, being passive, is easier to tame and collect, even in the UK meaningful amounts of power can be had with relatively modest investment. I think it's entirely possible to power my computers with a relatively modest solar array. I am looking at some solar panels and an inverter to go on my flat bathroom roof about 10 sq. Metres. Doing it myself, the cost would be modest but I am not yet convinced it's worth the trouble. As for other domestic appliances... I do have all the detail. Apart from my computer monitoring, I have ten accurate meters on most of my circuits, apart from my shower and the gas water boiler. I (almost) never use the shower and I am assuming the gas boiler uses very little electric. I will check one day... I only recently added comprehensive metering, at the beginning of the month when I was given a bunch of ex household meters made redundant by the new 'smart' meters, the old meters have to go somewhere, and I managed to acquire nine of them!

We are very green with 17 large sola panels on our south facing roof. Our electric bill was cut by half and the capital investment paid back in full after 6 years. Now 8 yrs in as I post this at 11.00am with blue sky and full sun they are producing 3.86 KWH, in summer at this time of day we get well over 4 KWH and still get a sizable quartley cheque.

Good to hear Graham. I am told that if all the Southerly roof space of the UK was populated with solar panels we would produce sufficient electric to supply the entire demand for the whole country. Storing it for overnight is the challenge. I am rather concerned both the bonnet being open on the Peugeot? Nothing serious I hope...

No 307 never gave trouble and still going well with my daughter in Kendal. It's an old pix first shot taken May 2016 when the D500 was new and Wendy has a new 308 now. Before we had a smart meter it was great fun watiching our old meter going backwards as we put power back into the grid. Yes we are thinking about over night storage but battery tec is not quite there and a bit ott price at moment.

Really. I must check mine as well then.
I have my MacPro with a boot 1TB SSD boot drive and two 540rpm drives of 1TB and 2TB capacity. The 1TB HDD is for swap disks and data storage and my processed or work in progress images are on the 2TB drive. All my RAW images live outboard on external drives connected via USB3. Also Lightroom (for cataloguing) and Capture Pro v12 have no problem working this way. USB3 is (almost) as fast as Firewire and eSATA so I see little benefit to upgrade to faster external connections. I am wondering if a MacMini (i7 4core) or iMac 27" i7 (2015) is better for processing. It seems that Apple are making the new MacPro the really power machine as expected but the iMac is close behind at a lesser cost.

As for storage, I feel that mass physical storage might be best such as the scheme being proposed for Australia at the moment, rather like the Dinorvic scheme in Wales where water is pumped between two reservoirs up during off peak and down during periods of high demand. No nasty chemicals or rare elements involved, just a bit of digging and some pipework. https://www.bbc.co.uk/news/world-australia-49202175 Edited: To add link.
