Really? That is rather lame. I guess you could use a multimeter like you said.
That's what I want. It's one of the main reasons I've gone with AMD the last few generations. Too bad the Lightning doesn't have the same kind of support because it's a pretty good deal at $550 vs $580 for the Classy.
They are both going to be pretty solid cards, the classified is probably worth the premium though as most of them have Samsung memory which the Lightnings do not AFAIK.
