the milion dollars question is "when" and how much time will take to these cpu's to fully be supported by game developers.The difference with Ryzen is that the "potential performance" does actually exist this time, and is easily demonstrated in productivity benchmarks. Games are achieving anomalously low performance in comparison, though it's still much better performance than anything from the Bulldozer family could even dream about. These are fixable problems.
I'know, cpu demand is not 100% by gamers, but still an important part of the market share.
Most important, how much time will take to have motherboard whith decent BIOS possibly out of the box? cause ii is frustrating to buy a module of ram only because the one you chose/already have dont post with the current bios and you have to update first
