Are you arguing?
They promised the 480 at £175 and we got that, very briefly.
Maybe it wasn't clear enough this time? It's definitely not new for them to do it.
Not arguing, showing you that they gave a 499$ msrp to the 64 without saying it was a limited time offer. THE NEW GPU KING under 500$ (but only for 15 minutes ....)
You're the one arguing.
There is no way to defend AMD, even AMD can't defend themselves otherwise they would have...
Take a step back, breath, come back and maybe you will see things with a different eye.
PS/ I could pick up a 480 msrp gpu 2 weeks after launch in France, we will see if the Vega follows the same suit, if it does and the vega 64 becomes available at msrp, no problem. What is important is what is going to come next, AMD could have easily came out and said "don't worry the card will be available at 500 msrp, you will have to wait for restock"
