Having a giraffe..
The Nano Fury and Fury X are typical AMD : technically they should be superior, in reality they're not, as Nvidia and Intel are better at implementation and that's what counts.
The Fury series aren't appreciably faster than NVidia's offering, they're not any cheaper, the drivers are worse and the connectivity on the cards is worse unless running an all Displayport estate, or the Sapphire Fury custom card.
420 quid? Not a chance. 150-200, might be getting somewhere.
