I voted yes, mostly because I already purchased a RTX 2070. Don’t care about games, only render speed which the 2070 was a very big step up from my GTX 980. I current.ly have both GPUs installed in my computer, the 980 for the displays, the 2070 not connected and just used for rendering.
As my main renderer is Octane I’m looking forward to RTX support. They are already getting a 3X to 10X speedup with the RT cores turned on. You can see the details here:
I haven’t had any issues so far with the 2070, Octane and Cycles render fast on it, and my OS is Linux Mint.
