2 of these, with a space between them preferably, should do the trick, IMO.The Sapphire R9 290 Vapor-X OC is the star of the show today. We feel the R9 290 makes more sense than the more expensive R9 290X. With the amount of overclocking headroom available on this Sapphire card, it is straightforward enough to outperform the fastest *[factory] overclocked GTX780 Ti solutions, nevermind a reference R9 290X.
That Gigabyte Windforce 780ti OC has a out of box boost around 1.2ghz, so it isn't shabby at all.
Its hard to justify the cost of R290X over R290, especially when you can get them with awsome coolers such as the Tri-X, Vapor-X and PCS+
My top card barely stays under 90c. I doubt 3 customs card would not throttle.
top card is at 90C with only 2. what is your spacing between card? 1 slot? or 2 slot? how is your case airflow?
initial planning for 3 non reference was to have
gpu1 in slot 1/2
gpu 2 in slot 5/6
gpu 3 in slot 9/10
allowing 2 slot between gpu.
with lots and lots and lots of positive air flow.
2 Asus 290x Reference + 1 Gigabyte 290x Reference + Startech DP2DVI is on route.
will find out real soon how many 290x is necessary to get the job done.
if 2 is all that is needed - as many of u have suggested. will under clocked all three for reduce heat (throttle prevention) and for reduce noise (skipping underwater).
2 Asus 290x Reference and Startech DP2DVI is here. There was some shipping issue with the GigaByte 290x so that order was canceled.
2 more Asus 290x Reference on order. Should be here be the end of this week for Quad 290x.
you read Karlitos thread on quad 290?
Karlitos culprit is 2560x1440 on the third monitor which output only via native display port. the DP to DVI-DL adapter is broken.
for now. I am running 1920x1080 for 1080p eyefinity on the third monitor so I do not share his problem. DP to DVI-SL is working fine.
in the near future. I am considering upgrading to 1440p eyefinity (30" Dell U3014 x3). Only ""IF"", again ""IF"" 290x x4 can deliver BF4 ultra setting at 70+fps and 55fps absolutely minimum. based on my research - this is NOT achievable with ALL the eye candy.
will not duplicate Karlitos issue. U3014 supports native display port.
1) RESULTS w/ 290x x2.
Resolution 6000x1080 (3k bezel compensated) - Ultra Setting - 100% Resolution Scale.
290x x2 simple NOT cutting it. on open map like silk road and close map like locker. getting average low 70fps with dipping into the low 50fps. on texture filled map like zavod, parcel storm, dragon pass, guilin peaks, and especially siege of shanghi (after the sky scraper falls) and caspian border. averaging mid 50fps and dipping to low 40fps.
2) STUTTER.
CrossfireX on the 290x is smooth as butter. If you think NVidia SLI (680 in this case) was smooth. CrossfireX is smoother. (this is confirmation for 2 gpu).
3) DX11 vs Mantle.
a) Mantle gets a 5fps gain.
b) Viewing distance or whatever you want to call it is definitely washed out somewhat. Feels exactly like that claritin clear commercial.
c) Slightly longer to load game. not a deal breaker.
d) Stutter was more pronounce (0.53ms). FLA calcaluator frame variance confirms dx11 is smoother (0.35ms).
Given the added fog to view distance and only 5fps gain and more stutter.
Staying with DX11. just add more GPU.

:awe::thumbsup: Hope it all works out for you as a fellow hardware nut and BF4 lover.
Or you could post evidence to back up your point of view?we can agree to disagree.
