I've had my ftw3 for a few weeks now and everything was fine until this morning when I had two pc crashes and windows said it wasn't allowed to access graphics hardware. Not too be alarmist though as there is no way for me to know for sure if it's a problem with the gpu, some other hardware or software.
I will say though both crashes happened while in Destiny 2. First one the game froze about 2 minutes in during a cutscene giving me that loud noise of the audio stuck that I'm sure we are all aware of. Second crash I went to the rr and then heard the windows alert sound followed by the destiny around turning off. When I got back to the room I had no video signal and had to do a hard shutdown. It looked like my pc was still on though just no signal which makes me think it's something with the gpu. Hopefully software.
Currently stress testing my gpu and it's doing fine so who knows.
*Edit* forgot to add that after the second crash I noticed all my precision x settings were gone like it was a fresh install. Startup settings gone and profiles gone.
