Nvidia announced the RTX 2000-series and the market reacted immediately with substantial price cuts for the Pascal flagships. Currently priced 30% lower than MSRP, cards like the GTX 1080 and 1080 Ti from Zotac are leading the "promotional offers." Additional price cuts could occur when the Turing GPUs hit the shelves in late September.

YES! This is the actual reason I've been excited about the new 20xx series GPUs. There will be a huge surplus of second-hand 1080 Ti GPUs going cheap because of the crypto currency boom.
That will be a lovely upgrade from my faithful old GTX 680
