Installed it yesterday - Borderlands 3 runs very well, a near constant 60fps on Ultra settings, but I’ll probably have to move around a few settings/sliders to get it more consistent.
I still haven’t tried Wreckfest or GTA V but I’d imagine they’ll run way smoother.
In terms of folding, after running for around 18 hours I went from around 48k points yesterday afternoon to 336k currently. The 760 that I used to have would take a whole day to return a WU whereas the 1660 now returns them around 3 hours, depending on the size of the WU.
All in all, a great purchase, I’m waiting on my new CPU cooler to arrive today to deal with the noise coming from the stock CPU cooler.
