AMD typically includes ECC support in "consumer" chips. Not all boards, do. I'm worried too, though, that this still hasn't been confirmed yet. An 8-core at 3.4+ GHz sounds perfect for a workstation.
A lot of motherboard manufacturers have stopped supporting ECC on their boards with recent AMD sockets but I think Asus is the last holdout.
ASUS is one of the few that lists it on their spec sheets. But I believe Gigabyte also supports it on a number of current boards, along with some other manufacturers.
I don't think any of the desktop APUs support ECC though (e.g. FM2, FM2+) (information on this is terribly hard to find).
ECC support is the norm with AMD CPUs. Even my cheap GA-970A-UD3 motherboard supports it.
