I was considering getting two of the 8gig Sapphire 480's. Maybe even water cooling one of them. Money is not necessarily the issue, more so patience with waiting for AMD to get off their collectively lazy asses and ship Ryzen and Vega. >:|
Maybe use the two 480's as the focal point/transition piece with which to transfer to an all AMD build over the next year.
And I already have 1 Sapphire 480 in the mail as I write this.
What I wanna really know is: works crossfire in Linux better than in windows?
I really like my XFX 480 8GB but for gaming in 3440x1440 I do need a bit more power but crossfire under windows seemed a bit odd since microlags are still not fixed.
Much to my surprise the first one showed up today in the mail. Like, an hour ago. Fresh install of Linux and almost have a game downloaded for first test.
I think that you should return it because Crossfire might be an issue. I think a 1070 is the best choice of GPUs at the moment. Waiting for the AMD Vega cards might be the best thing to do but I see that you're a bit impatient lol.
I got the proprietary driver working on Ubuntu and the open source one on Antergos. In both cases the card does pretty good. HDMI audio out only works on the pro drivers though. I think I will keep this card and build an AM4 computer around it, eventually upgrading to a Vega.
EDIT: Apparently I do not in fact have the pro driver working correctly.
I would hold off for a single vega card myself. Even under windows not all games are coded well for crossfire / SLI so all the GPU horsepower from 2 card can go to waste often.
Linux well my RX 480 is a little disappointing. No driver GUI and 2 games dont work on AMD when did on Nvidia on linux. Im hoping the driver (AMDGPU) will take off more with vega's release.
