Say maybe ASUS and Gigabyte > XFX and Sapphire?
There is no difference between them, the only difference is the stick on the card and the after sale service.
That is correct
Regarding the 390 rom, will update OP this week for sure! "Been updating some other things first.."
That is great. We would like to see some updates on the R9 390. It is a great card, and needs some power saving.
