The only pertinent question is: "Will it support NVLink/SLI and what about 3 or 4 way SLI?
EDIT: This guy says the 2nd gen Titan RTX will be slower than the 3080 Ti / 3090? wut?
Lots of people have argued over the years that Titan is NOT a gaming card. Maybe nVidia is finally making that an undisputable fact, moving forward by refocusing clearly on compute. Hence, the 3090? Just a guess.
