puget released some test benchmarks they ran
for the most part the two cards perform similar. the gtx 1070 has some new features like HDR and will also use less power and should be quieter. generally the gtx 1060 6gb would be recommended to the 6 core cpu, unless special needs require something else. the gtx 1060 6gb should be around 2x faster than the gtx 680.
some news came out about memory issues with the gtx 1070
the 1060 is farr behind with preview render :s
is the 1060 going to double the speed from my 680 ?
depending on the article, those results are from 10 core cpu or dual xeon, and they also list what media and fx were used. you have a 6 core, which will limit how much it will push the gpu and your projects may be completely different then what they tested. the gtx 1060 did poor in 6k red media and a couple of 1080p preview generating benchmarks, but most benchmarks there was little difference between all of the cards.
i don't have premiere benchmarks of the gtx 680 vs 1060, but some game benchmarks will place it around 2x faster. it would also depend on what is being done in premiere or other software to determine how much faster the gtx 1060 would be. if the software is bottlenecking on the cpu, the gtx 1060 might only make a minor improvement...
you can use GPU-Z to see what the gtx 680 is doing.
I will try to run my GTX 680 tonight and compare it to my GTX 1060

You are in a Premiere Pro Hardware forum and I know nothing about Lightroom and your conversion and transcoding processes but I will guess that they are highly CPU intensive operations look at Task Manager/Performace to see if they are CPU intensive and using something like GPU-Z see if they use the GTX 680 (Sensors TAB). To many people believe that upgrading the GPU is a magic cure for performance without knowing what is really causing the problem. If they are CPU intensive operations then your money would be better spent on (for instance) an i7-5960X.
Now for 4K Premiere editing it should be an improvement just going from your 2 GB of Video RAM to the GTX 1060 6 GB. But also if you really are using Premiere Pro's GPU accelerated effects then you will also see performance improvement. My Premiere Pro BenchMark (PPBM) test the hardware features of Premiere. There are four hardware tests:.
- A Disk I/O test
- A CPU intensive test
- A highly GPU intensive test
- A GPU intensive test with many different media formats including some 4K media.
With my i7-5960X at 4.5 GHz the CPU intensive test is 265 seconds, That same timeline when you apply GPU acceleration with the GTX 680 I get actually about the 27 seconds with both at stock speed. But by a very simple and safe overclocking you can get down to 19 seconds. The much more complex H.264 timeline with 7-layers some and 4K media takes 460 seconds without any GB assistance and with the GTX 680 and GPU assistance i got 88 seconds and with the overclocked GTX 1060 it drops to 56 seconds. But some of that improvement is not do to more CUDA cores it is do to the Video RAM as it goes up to 3.88 GHz as you can see below.
Huge thanks for your benchmarking!
I am going to order a 1060 and see the results.
hopefully it will be enough so i don't need to upgrade my cpu.
