amd mainstream and highend users will have to wait until steamroller fx series for pci-ex 3.0 to be officially supported. kind of backwards how amd releases their products the affordable ones get the latest tech while the mainstream and highend will get it later.
Probably only 5% of AMD systems are AM sockets now. If you're ONLY factoring in Desktops, especially DIY machines, then the numbers change dramatically. But guess what? That's not mainstream anymore, and therefore AM3+ is not mainstream.
It absolutely makes perfect sense to prioritize mainstream, entry-level, and now ultra-low-power markets. In other words put the latest into their APUs and their supporting chipsets first. I don't like it, but it's only logical. Realistically, if they didn't do this, they would die off. Even if they do, they've got an uphill battle, but there are many fronts where they're doing well enough.
I still don't have to like it.
