GREAT stuff, thanks very much both of you.
Vince : I'm hoping to get a universal VGA block soon which I can then carry from card to card. The reason I've never got a full cover block before is they're so damn expensive, I don't think I could find any available anymore for this card anyway because as you say, it's quite old now.
I certainly can't afford a new GPU but this RX 480 plays my games close to max settings which I'm happy enough with. (FYI : Insurgency Sandstorm, Overwatch, WRC 7 and Steep)
