Pros: Fast and stable if you get a good chip

Overall Review: I spend three weeks building my last computer. It would not load an OS (either Win10 or Ubuntu) -- the computer would simply freeze half-way through the install. It turned out the lightning does strike twice. I had a bad motherboard (which had other problems and I was sure was responsible for the hanging), but a NEW motherboard would still hang. I blamed everything else -- Graphics, Ram, Power Supply. Finally, I went to a generous friend (who understands AMD devices intimately), where after much switching of procs, memory and power supplies, we proved that the proc had some sort of internal damage. Mind you, the proc would stay stable while in BIOS and ran all kinds of tests just fine. I finally RMA'd it. The new chip (bought elsewhere) works great.
