Yeah, not many feel this way or understand this. But I feel the very same way. I got the money, but I want what I perceive to be value for my money!
I got a MSI R9 290 well over a year ago on members market for £135 which was great value to me. Then I got a XFX Radeon 295x2 for £330 I think it was, which served me very well. I got to play all the games I wanted at 4K, like Crysis 3, Tomb Raider etc which worked perfectly with xfire. But after I was done with my back catalogue of what I wanted to play and new games came out which did not support crossfire for month's after release, I got annoyed with it and sold it for a very nice profit.
As a matter of fact I could add £70 on top of what I got for my 295x2 and buy a cheap 1080. But I won't, because the 1080 does not represent value to to me, as I was expecting more from 14/16nm and feel that 1080Ti and Vega will be at least 50% more powerful than the 1080 and not cost a lot more.
Anyway, rambling on now. But I was hoping the 480 would represent good value for me until Vega comes out. Then it would go in my partners PC. But as time goes by, I am not so sure.
