4-way crossfire Firepro

[X-Gamers]

This really could be related to any firepro crossfire but I was considering the w7000 for a workstation I might build in the future. Has anyone done 4-way with professional cards? and if so please enlighten me on real world performance/issue if anyone has done this type of configuration. Please and thank you. Also I was wondering about possibly just using 3 and getting a quadro or vice versa for both openCL/cuda.

Well, it does help in some workloads. And AMD Crossfire is the way to go for multi-GPU configurations since Crossfire scales better than SLI.

So can I crossfire three firepro w7000 and have a quadro. Also if I do that configuration would I use the card for video output that's the closest to the cpu or not?

I wasn't aware that workstation cards crossfired. I thought they would work together, without the need to SLI/CF.

What am I looking for on that post? There is nothing there that says a thing about Crossfire.

I read an interesting reply to another post on this: http://www.tomshardware.com/forum/374659-33-crossfire-firepro-v4800

Confirmed by calling AMD themselves, the V4800, even though it has crossfire connections, it is disabled on those cards, and that's probably why you don't hear anyone talking about it. The guy said, the lowest card in the firepro line that starts supporting crossfire would be the V5900 which is about 300 bucks more. Go figure.

So, apparently some of the Firepro's can, but just because it has the bridge connections, doesn't mean it is supported.

Going here to their FAQ and workstation cards are never mentioned: http://support.amd.com/en-us/kb-articles/Pages/AMDCrossFireFAQ.aspx

I personally wouldn't try to Crossfire professional cards, the results are going to be inconsistent at best. Crossfire isn't needed for professional tasks, they'll use multiple cards without the need for Crossfire.
