ATi 3870X2 = 1035Gr.

What driver ? :p

what driver for what? Quad CF? the latest Catalyst.

With XP ?
Don't think so.

you are correct!

Note: CrossFireX™ (Quad) is only supported under the Windows Vista operating system

very weird, must have misread somewhere along the line

Honestly John, show me two 3870X2 working properly in XP please ? Haven't found any so far (only Vista).

Edit : never mind :p ;)

Quad-CF in XP works, but Ati will never launch the drivers.

honestly Torsten... read before you post! :p

I was writing my reply while you posted... took me a whole 20 minutes to come up with that line :D (in truth, got a phonecall while I was posting)

Anyway, I think we all get the picture now :p

Try Catalyst 8.3, these are the only drivers which currently support Quad CrossFire :)
