The best bet may be to keep the powder dry til next year when Nvidia will release 7nm GPU. There will certainly also be a bump in CUDA core and RT chips. The Ampere family 3080 TI should be one hell of a card.
Of course that release time could drag out so there is risk in waiting…
Meanwhile there are rumors AMD could launch a 64 core/128 thread Threadripper in Q4.
I’d likely look at the 32 core version of that chip. If that product isn’t 7nm I will likely go for faster clock speed, save money and opt for the 16 core 3950x
