To be fair, Gibbo sells motherboards. :P Later in the originating thread he talks about the MSI Pro Carbon as being a 'high-end' board and MSI is well-known for using NIKOS components on boards in that price range. This tells me that Ryzen overclocking will be limited on phase-limited boards and boards with weak-link VRM but boards with decent components and good phase designs will overclock well. It's obviously a sliding scale and the absolute best components will overclock the absolute best, but that also costs and the vendor has to either cut corners elsewhere (features, PCB quality, etc) or charge more. I haven't yet seen a board I want to spend a bundle on yet. I'm sure they'll come in time, though.

Also, there isn't any Biostar available locally. I'm getting my hands on one, but only because my sister lives in New York. Really, though, overclocking will come down to what it always comes down to. Heat and power management. Every board that isn't like a Rampage or something makes compromises somewhere. Know your caps/chokes/MOSFETS and determine whether a board can handle what you're throwing at it.
