I have one of their GTX 960s, and it's been rock-solid even when it has been continuously crunching on BOINC projects for months on end.
I was hoping that the crash in crypto mining would bring some sanity back to the GPU market, but (like all too many things) it's really not a market after all, and sanity is too much to ask for.
I'm sad to see them go as well, but if they can't make money building graphics cards, then I don't blame them for getting out.
