Not only this, it doesn't change the fact that it adds to the cost. Also, I doubt the cables are cheap right in this case?
Does it work with freesync?
Really, this is more interesting just for the people who may not have Maxwell cards as a whole rather than to solve the Fury X/R9 Nano being aimed at 4K gaming cards that can do HTPC.
Now, you can use your R9 290, 780Ti, etc. so that's probably more exciting than just focusing on R9 Nano/Fury X, which to me is just ridiculous that they didn't include it.
Would have been interesting to me before, but now that freesync is coming to monitors over 55 inches, I couldn't care less about the traditional TV market. It's dead to me lol. Still will need a projector, if Freesync ever came to projectors..... The things I'd do to make that happen are unspeakable!
