QA on their refurb units is definitely out of whack.
I bought a B-Stock GTX 580 from them which was rendering artifacts iirc. A replacement 580 also rendered the same issue. The next replacement was a seemingly new GTX 960 which has worked without issue ever since. Having received a $200+ card for $80 + some hassle was a net positive experience in the end for me.
