Hello,

I like to keep up-to-date with this kind of stuff.

So with the new ATI cards you're now able to use 3 or 4 cards right? but with the heatsinks on there they take up 2 slots, so how can you fit 4 onto a motherboard???

I think this applies only to the 3870s not the 3850.

As far as I know, both the 3870 and the 3850 can have four cards running in Crossfire. Each PCI-E slot is two slots apart, so even though the 3870 is a two slot cooler, they can still be put in the same motherboard (you SLI 8800 GTX's :wink: ).

I would wait until the release of the 3870XT soon in Jan then just crossfire them = pretty much 4 3870's.

I read that the bios revision to allow 4 cards will come End Jan /February.

I think the HIS 790FX board can take 4 with heatsinks on. Not 100% though.

The 4-way crossfire is supposedly only able to do so on ATI's own 790FX chipset. Not any other, not the 790X, any Intel...just the FX. They have to pimp their platform too. Even with dual GPU cards, you'll need a quad-able chipset to have all four function.
