Hi, the new card has lower temps, like max 78C on stock frequencies. It maybe because this one uses Samsung memories, I don't know.
The BSOD is still there but with new drivers 417.71 and 417.75 the game is freezing and if I press mouse exits to windows.
Nvidia is still working on BSOD problems, because is not the only game it seems, and now they have problems with the freesync monitors also.
I think the old card had a problem with power, because on this one I noticed while playing on the onscreen display from riva tuner that the power draw is more constant under load and I mean that it is constant about 98-101% under full load. On the old card the power was allover the place from 80 to 110 and even fluctuating in a higher range then this.
This one I feel that is more responsive.
Your problems may be from the PSU. When I bought my card after 2 days of testing, I turned off the PC and went to sleep and in the morning my PSU (Thermaltake 750W) decides not to start. It was just starting and turning off.
I was scared at first because I thought that the videocard died. It was weird because I was sleeping with PC off, and when I shut down the PC the card was working. I replaced the PSU with an old trusty 500W PSU and it worked. But with the 500W I turned down the Power limit to minimum.
Although the 750W PSU had all protections, it seems that in fact some circuits from the PSU died the day before I turned off the PC, because it seems that, that card, because of the power jumping allover, was drawing with the whole system more then 750W.
That's why think that 750W is not really enough in some situations with rtx 2080 Ti.
Now I have 1200W PSU.
I don't know what CPU you have exactly, but on some mainboards, it comes default with all core boost because manufacturers wanted to have the best mainboards, and this is not how Intel recommends, because it can draw more power then usual.
I think that you should check the power consumption under load of all system, or try another higher power PSU. That reset can be from system not having enough power, or CPU undervolted for all cores to run at 4.7 Ghz. It can be that the PSU is broken.
I will try time spy also and tell you if I have any problem.
