Hello Dave,
thanks for the info and hope to see "RTX 2080 Ti" benchmark soon.
Titan-V is too expensive for us. I expect that "RTX 2080 Ti" will be
probably a good
compromise between "GTX 1080 Ti" or "RTX 2080" and Titan-V.
For those who interested, here is for the moment at least comparison of
performance above mentioned GPUs in "Machine Learning (Deep learning)" .

Best wishes,
Marek
