Hi 
I am considering getting a new GPU to improve Premiere Pro export speed and am trying to get an idea of the value of the investment in terms of the realistic expectation of actual time savings.
Current Build
Motherboard: Gigabyte Z390 AORUS PRO WiFi
CPU: Intel i9-9900K
RAM: 64 GB (4 x 16GB) 288-Pin DDR4 SDRAM DDR4 3000
GPU: NVIDIA GeForce GTX 1060 6GB
My GPU is clearly the bottleneck for my Premiere Pro export speed. The CPU is generally at about 50% capacity during export and the GPU is at 100%.
Footage is usually recorded at UHD/4K and is color graded.
From my research so far it seems that in terms of value for money, the sweet spot for GPU-heavy Premiere Pro processing is the RTX 3060 ti.
Is there any way to estimate roughly what sort of time savings I am likely to get by upgrading from a GeForce GTX 1060 to a GeForce RTX 3060 ti?
Realistically will a 20 min export time go down by 3 min? 15 min? somewhere in between? no way to predict?
Thank you!!!
