Well yah, the new cores may help or hinder mining. Will have to wait and see. Expected to be 30 percent faster which doesn't always mean faster mining. Still waiting for that 70-80 mh ethereum card.
This +1, but to my mind as they see their cards are great for mining too, I highly hope their upcoming RTX 2080 will be great for mining + nvidia isn't company which sells GPUs cheaply, this is another bonus for them to sell GPU in high price and have high supply/demand.
BTW curious is that when I google GeForce RTX 2080, google displays: Showing results for GeForce GTX 2080.
