£230 ^^^
So the suggestion is 960 / 380 owners are interested in this?
if they ain't buying 970 / 390 for £250 over the past year they ain't going to do it over the next year just because its more power efficient.
Get a grip Humbug, seriously.
Firstly $230 isn't £230, it's only that if you let yourself be ripped off, nothing more or less. $699 is £473, + VAT is £567, the cards were £619 on launch which is a SUB 10% markup and still not at all £699. £699 from £619 would have been a further 13% markup that didn't happen. $299 as above is £155 + vat £185, even with the 10% mark up would only be £204. You've gone from elated into crazy and now you're just making stuff up as you see fit. It's £300 because you've decided. Honestly, it's embarrassing reading your "it's epic" "it's worthless" up and down takes on this card where you do a complete u-turn over a bit of information that makes no sense at all.
Secondly, there are several hundred million PC gamers, the MASSIVE majority don't have Maxwell, Pascal or GCN based chips. If you have 500million pc gamers and between 40-80mil replace their GPU per year.... realise that it means that most people don't replace their gpus yearly, the monumental majority don't replace them within 4 years.
A huge portion of the market buys a new PC or a new graphics card every 4+ years and many people with 7870s, 7670s, millions of computers used to play WoW, there are literally 10's of millions of people who only upgrade infrequently and will end up with RX 480s sold inside an OEM computer.
Enthusiast level consumers upgrade every 1-3 years, the majority of the market does not. There are also lots of users with cards like a 960/380x who will upgrade to an RX480 as well.
