Of course it is interesting (for everything but modern 3D heavy PC games), and although I'm no super specialist to judge all specs I see this Vega's core clock is up there with other mid-range discrete video cards like the RX 580, which I can't find under 185~189€, so yeah value definitely is a strong argument.
I think we've briefly exchanged on the topic somewhere so it'll be redundant but heh; mystery remains though in regards to how much shared memory matters in general (and therefore how much you should spend on it) then for GM use specifically.
Also redundant; what also bothers me with Ryzen is that FreeSync (for those who want to keep the option) works only under rather obscure and ill-documented conditions, for instance will FS work through HDMI with that mobo and with which monitors exactly? : please publish a paper if you find the right and reliable info, because Ryzen users otherwise have to buy much more expensive mobos featuring DisplayPort if they want to be safe (add +100€; bye bye better value)
For that reason - I'm being paranoid here but - because I don't like their (AMD's) obscurity I can't help but worry about the actual handling of analogue/VGA too.
It'd be baffling that it wouldn't work fully as in any other discrete GPU w/ analogue out configuration, or if for whatever reason it would reject non-common/non-PC resolution modes, like it'd be a low-cost legacy, fake VGA out.
But I wouldn't rule out the scary possibility, because these days no manufacturer will care about the infinitesimal number of customers that might complain if an analogue out isn't a full-feature one.
Again, paranoid...but heh.
