Quad SLI doesn’t work on XP !
 

If you are after Quad SLI with two 9800GX2 cards you can forget about playing under XP. Nvidia clearly said that at least for the time being Quad SLI driver works only under Vista.

Both Vista 32 and 64bit are included but so far the current Forceware 174.53 for XP doesn’t have support for Quad SLI.

HD3870X2 CF does work in XP :D

... from time to time ;)

With what driver ?

3-way sli doesn't work on XP, why would quad-sli work in xp then?

(remember how the previous quad-sli drivers for xp sucked?)

uhm Quad CF works better in XP than in Vista, better performance scaling in XP vs Vista

FYI ;)

Tell Geoffrey that... might get his setup running then.

driver issues are not new for either NV or ATI, when it works Quad CF scales better on XP vs Vista according to benches found on the WWW!

That's why I would like to know what drivers :)

Cards arrived, they are massive, never seen such a heavy and large card....

indeed, you haven't seen 9800GX2 yet, they weigh 1kg ;)
