Day one for sure. The question will be how long for it to stabilize. As we know, Ampere stock is still non-existent, and we are going on 2 months since they became available.
There's no way I will getting this card anytime after it's announced. I can try and dream but it won't happen. I've been meaning to redo my build at some point and if the 3080ti rumors are true then I can keep my current monitor for now.
But it does not look like I'll have something other than a 1080ti until summer time 2021 if I'm lucky.
I remember getting the current card I have now, it was difficult the first month. After that, I could easily add it to cart from any shop on a weekly basis.
I figured they just wait until AMD released their competing product and then drop the price of the 3090 to maintain their desired price gap. It's not like they haven't done it before.
Actual AMD reviews by third parties will be out soon hopefully in December and then they will be forced to drop the price of the 3090 IF they actually go forward with releasing of a 3080Ti in that January time frame.
