    I have a GTX660 2GB and am wondering if upgrading it will have meaningful impact on editing and encoding 4K h.265 & h.264 clips using CC 2015 Pr and AME. I do a lot of encoding to preview h.265 100Mbps drone footage (4K TV only handles max 50Mbps).

    My 3.06Ghz 12c 64Gb cMP handles playback pretty well on Pr timelines, but I'm only previewing in HD as I don't edit with a 4K monitor. I note that CUDA is best encoding performer in AME over OpenCL or CPU only - but I'm not sure what is more important in a card CUDA cores vs RAM vs clock Mhz? yeah, yeah "all of the above"...

    I don't want to blow alot $$ as I don't game on Mac...I put a few parameters into an xls to help me compare a couple of options of 2nd cards I see in my local area...I came up with a score based on cuda, clock, ram and price relative to scale of 1 being my old GTX660 which cost me $199 new a few years ago...the GTX1070 comes out on top basing on 2nd hand prices (AUD).
    The score is cal using my GTX660 as reference i.e. new core count divided by gtx660 core count multiplied by clock speed, similarly for ram then minus relative value of price to obtain overall performance-value...980ti just for comparison I don't wanna mess with power options of risk reliability.

    I would probably go for the GTX 1070 (you'll need a 2 x 6-pin -> 8-pin PCI-E power adapter). As flowrider said above though, you can get the GTX 1070 for a lot less than $500.

    Performance is pretty much dependent on the amount of SPs (CUDA "cores") and the clock speed they run at. RAM is a secondary consideration.

    A second hand GTX 980 is also a good option (good GPU compute performance and reasonable power consumption).

    The GTX 1080 is getting pretty close to the $400 mark, so there's not much of a reason to buy a 1070 unless you can get it for about $300. There's a Gigabyte 1080 on eBay via Newegg for $439.99 right now and the EVGA FTW DT 1080 was $447.26 on Amazon today. I wonder if they'll drop more when the Vega is released.

    Prices in AUD for relative comparison, I'm Downunder & we get pay more here. 1080 is very exxy here

    Since the GTX 10X0 are not being built anymore, it's my opinion that prices have bottomed out and as they become rarer, prices will start to increase.

    Can you cite your source for that information. The 1080 Ti was recently released and so was the regular 1080 with faster 11Gbps memory.

    ^^^^I'm not talking about brand new equipment like the GTX 1080Ti or the yet to be released 11GBps GTX 1080, but equipment that is from a prior release and is end of life. And, if you read my post I did say MY OPINION. The original GTX 1080 was released on 5/27/2016, the Ti version on 3/10/2017.

    i always look to pugetsystems articles for things like this (tho it's windows testes i assume it will be close scaling on osx but slower thanks to old cpu's ect on mac)

    PP pascal GPU performance 980ti to 10x0 cards + titan x
    https://www.pugetsystems.com/labs/articles/Adobe-Premiere-Pro-CC-2015-3-Pascal-GPU-Performance-840/

    so id gess 1060 6gb

    this may be fun to
    https://www.pugetsystems.com/labs/a...rdware-for-your-Premiere-Pro-Workstation-916/
    22 min in a gpu section
    30 min vram rule of thumb

    o and dont forget fast drives ;)

    (i think the speed up is vary small once you have a gpu for most tasks but once you hit 4K then you want 4GB vram but not the fastest card, or that used to be how it was)

    So you think last year's 1080 cards are going to be discontinued rather than kept at a lower price point? The new 11Gbps 1080 cards are already out.

    Here's an MSI: https://www.newegg.com/Product/Prod...K1xEV8rQPbVWQMTuU5UYcaApIh8P8HAQ&gclsrc=aw.ds

    And here's a Zotac: https://www.newegg.com/Product/Prod...DZQzzxWBcg45M1RATD7g4aAiA48P8HAQ&gclsrc=aw.ds

    Here's a review for the MSI 1080 11Gbps card: https://lanoc.org/review/video-cards/7504-msi-gtx-1080-11gbps-gaming-x-8g?showall=&limitstart=

    It looks like a good value. The performance sits in-between the regular 1080 and the 1080 Ti. I saw a couple benchmarks where it actually out-performed the Ti and it's able to maintain 30+ FPS on Ghost Recon Wildlands with ultra setting on 4K while the regular 1080 couldn't manage that.

    ^^^^Didn't realize that the newer cards had been released yet. Yes, faster RAM for the GTX 1080, 11GBps vs 10GBps. The GTX 1060 and the GTX 1070 has also been stepped up from 8GBps to 9GBps. These are replacing last years offerings.

    And, yes, it is MY OPINION that these new offerings are replacing the old offerings who have had rebates and price reductions for the last month. And yes, IMO, when the pipeline is cleaned out, last year's models will be history. Now, IMHO, is the time to buy last years offerings because they are at their lowest price point before they are gone.
