Not tried it yet on two separate 3870 yet , but I did have two 2600 Pros folding together
As far as the X2 I don't think it works that way.

You must have one CPU thread for each GPU.

EDIT: I know CD has his folding on both of his HD3870x2s.

I think if there was a way to do machine id 3 or whatever and download second instance to a different folder then possible maybe.Thanks

Its something like that for dual noncrossfire set upcards.
ATI GPU2 with two cards below
---------------------------------------------------------------------
What about multi-gpu support and the -gpu switch?


Running multiple GPU2 clients, one client each on multiple GPU cards, is supported through the -gpu x command line switch. The setup is similar to running multiple SysTray CPU clients.
  • Copy your \\Application Data\\Folding@home-gpu folder to a new folder \\Folding@home-gpu2 (\\AppData\\Roaming\\Folding@home-gpu in Vista)
  • Create a new shortcut for the first client, and be sure to use the correct Target: and Start In: information. Note that one has to be very careful with shortcuts, and in particular, make sure that the "Start in:" field is set correctly. If you are having problems with automatic core upgrades, it is likely that your short cut is not set up correctly.
  • Edit the shortcut properties to add the -gpu 0 switch to the end of the Target: field.
  • Create a new shortcut for the second client, and be sure to use the correct Target: and Start In: information.
  • Edit the shortcut properties to add the -gpu 1 switch to the end of the Target: field.
Except for the different -gpu x switch, the Target: field in both shortcuts will point to the same FAH executable. The Start In: field for each client will point to the two different \\Apps Data\\FAH folders. The Target: and Start In: fields for a SysTray client are explained in more detail below.
The display must be active on the GPU card you plan to use, and –gpu 0 will select the first board, –gpu 1 will select the second board, -gpu 2 the third board, and so-on. You will need to disable crossfire for multiple boards to be detected. You will also need to use different Machine IDs for each client. Currently, only one client is supported on a 3850X2 or 3870X2.

Wow, this guy got his 9800GX2 to fold on both GPU's doubling his points! I'm assuming 2x GX2 cards would quadruple the single GPU points in SLI. Anyone want to try getting a quad SLI MB to put out ~35k ppd?

Man, this is getting pretty wild, I love it!

I'll be folding with my QX9650 @4Ghz and my dual R700's in August
