I shouldnt think so as a standerd non xfire board supports one x2 isnt it safe to say that a sli board would just treat these cards as 2 cards and then the cards would do the work to COOP as 4?
 
I believe the X2 counts as a single card as far as the PC is concerned, so a Crossfire board SHOULD take 2.

The 4 way crossfire boards are for if you're using standard 3850/70s I believe.
 
Looking at the specs on the gigabyte X38 DS4, ocuk state its:

"crossfireX enabled with true dual PCi-e 2.0, x16 slots"

So theoretically, any X38/X48 mobo should run two X23870 cards fine I'd have thought.:)
 
gigabyte says its crossfirex on its site as well - checked othr day incase wsas a typo by overclockers but its there.
 
With your clock running at 4.5Ghz on a quad, those cards are gonna run very nicely :) I bet you'll see substantial gains if you can clock even slightly higher though, given how much demand will be placed on the cpu by four gpu's.

Look forward to the results :) (when drivers are available of course).

As far as I was aware, no chipset is actually needed to run crossfirex, which is the limitation of sli, that it needs a motherboard chipset to work? I see no reason why crossfireX won't work on any 16x + 16x board.

How much did you pay for the 3870X2?

If he didn't get them from OCUK, he can't talk about prices (he does NOT state where he got them).

Cupra, You clearly have pretty much the best of everything on your system, but just one thing: With such a large demand on your system from 4 gpu's I'm thinking that maybe overclocking the gpu's won't result in big improvements unless your running massive res, and huge amounts of AA+AF+HDR etc, as you'll 'probably' be so cpu limited anyway.

I'm excited for the results, but with the above in mind, can you record all results with 4-way and 2-way crossfire please to see how overclocking the cards is affecting the demand on the cpu? More of an 'interest' thing rather than me being crazy enough to buy 2 X2's (wife would kill me).

yes thats right... crossfirex is for up to 4 gpus.. crossfire is up to 2 gpus..

i really can't see how 1 3870x2 would work on a nvidia motherboard. because crossfire needs to be enabled so 2 gpu's will work..

The crossfire controller is built into the X2, so it will work on any mobo with a PCI-E 16x slot.
