Sounds great but compared to your 8x780Ti which score almost 900 investing in X is not that attractive (unless you need 12GB). What do you think?
Here's my view on GPUs (and other related things). Things are changing so rapidly that 1.5G, which was a lot when the 480's and 590's were released, is extremely puny today. Moreover, a lot depends on one's use-case. Almost as soon as you purchase GPUs, particularly the highest end ones, they'll become second fiddle within a year, but they aren't obsolete. I still use my many GTX 480s and 590s, and with out-of-core technology, that 1.5G limitation is being greatly removed, tho' not exactly the same as having 12G GTX 480' or 590's. But things do change: what may first appear to be becoming a limitation with a high end product as time passes may be remedied somewhat by new technological/software accommodations to suit what the great masses of that particular buying public have to apply to that task , for they may not even have purchased the high-end. Nature abhors a vacuum and software authors abhor excess capacity. I doubt it's take 5 years for 12G to seem puny because of new applications and advancements in currently existing ones. Additionally, in 5 years, if my shell endures, I'll be sixty-seven and I'd like to reach the point of having the pipe dream stable set/size render farm (but I know deep down inside I'll always desire at least one or more of the then current top -of-the line
to add to my old stuff. So although, my GTX 480s have ragged teeth, I still use them. A wise person on MacRumors MacPro forum captured it nicely when he mused that we can never truly future proof a thing of technology, but that we can try to make our purchase decisions future resistant. So, that's how I view those Xs, simply an investment in future resistance, but soon to be outperformed March 2016.
P.S. I've never regretted having the top-of-line; I never lamented that my CPUs or GPUs had too many core or ran too fast; or I that had too much ram or Vram or they they operated too quickly; or that I had too much storage or that my storage operated much too fast. Technological innovation springs from nature, so they both abhor vacuums.
Because I have 180+ GPU processers in 16 tweaked/multiOS systems - Character limit prevents detailed stats.
