Snips I have the same cards as you and have been using the same driver since well before taking my 780 out. Single titan, SLI, dual titans in non SLI, 780 and titan and about 15 different BIOS's and they have been solid. 347.52 iirc.
AMD I have only used 1 driver and a sample size of one is as relevant as a sample of none.
I never bother uninstalling old NVidia drivers, I just do a clean install over the old ones.
The only time I use DDU is to get rid of old bits of AMD drivers as these do cause problems sometimes.
I think this may be a good time for me to get may hat and coat.![]()
I get that, honestly I do but there was as reason for uninstalling the drivers. Booting the PC up in the morning, rebooting through the day would cause the monitor to go black, with no picture and I'd need to disconnect the DP cable & monitor power to get it back.
^^This is why I uninstalled the drivers to fix this. I don't normally remove them like this when updating them, I just, as you've said above, do a clean install or just install over the top!
