After installing my thermal pad kit and shoving in the Powerlink adapters, I figured I might as well go all out and try those new drivers. Didn't even bother doing a DDU or anything like that, I just let the installer do a clean install and tested them out.
With the old drivers I did a few runs in the Rise of the Tomb Raider benchmark as well as Unigine Heaven and they both seemed low to me. ROTTR used to be at around 140 fps (all maxed 1440p), now it was at only 127 fps. I noticed during the Thermal Valley part that one of the cards was screwing around with only 50% GPU usage, and I did notice some slow down in the game as well (Bloodties DLC in Croft Manor). Heaven was way off as the pics below demonstrate. The new drivers made quite the difference in ROTTR as well bring the score up to 157 fps. I haven't tried too many other tests yet, but these two look encouraging.
My overclock was not changed, I kept it at +375 for the memory and +75 for the clock. Temperatures seemed to be a bit better too with a prolonged Witcher 3 stint never exceeding 80C (was as high as 83 before). Games that don't utilize SLI ran rather cool too with one card running, it never exceeded 60 C in Forza Horizon 3.
Will have to do some more testing, hopefully I won't find any issues with other games and tests.
What's your experience?
