Which AMD setup should I go for?

[nerdoftheweek]

Hey guys. I recently found a steal on a new 4k monitor, it has support for freesync and not gsync. So I was wondering what configuration would be best. Currently the strongest competitors are dual 390X's or a single Fury X. What is the best option for around $700? (Note: I will be using an Intel i5
and 8gb of RAM in this system)
Edit: Monitor is AOC U2879VF if you are wondering

In games that support Xfire the two 390xs will offer more raw performance.
However, the FuryX will run cooler, much less power, and less compatibility issues than two cards.
The FuryX is only 20% faster than a single 390x.

I would go dual R9 390 the X version is not worth the price difference.

Well the 390x's will be more powerful, but the Fury X will be more stable and quieter.

You've also got 8 GB or VRAM on the 390x's and only 4 GB on the Fury (it is HBM though).

Have a look at Tom's Fury X review benchmarks, and be aware that two 390x's are roughly equivalent to a 295x2.

So from what I can tell (sorry, new to red team) Fury X is basically the green's Titan X in that it's basically not worth the upgrade from the previous card? Also, am I going to get any issues with dual 390x's (or 390's)

No more than any other dual card setup.

See, I've never done dual card setups so I am nervous to start, but if it is worth it I would be willing to learn, if anyone could tell me/defer me to somewhere I can learn pros and cons and problems that may arise with dual card setups, that would be great

I have run a couple of them in CF 2 x HD6850 and 2 x HD7950 no issues apart from 1 or 2 games not supporting it.

If you're considering Crossfire (or SLI for that matter) it's worth reading a section of this post: http://www.anandtech.com/show/9874/amd-dual-fiji-gemini-video-card-delayed-to-2016
About half way down is a heading, "The Current State of Multi-GPU & AFR" - that's the bit that might interest you. The author is pretty pessimistic about multi-GPU setups, at least until DX12 and/or VR become much more widespread.

It's just one perspective and others will no doubt see it differently, but worth your time to read and consider I'd suggest.

Is the 295X2 considered a crossfire or a single card in game? (i.e. will I still have any trouble as far as games that don't support crossfire)

 

[Gam3r01]

It is considered to be Xfire (two GPUs in Xfire on a single PCB)
