Will a double slot video card fit in an ASUS P5Q PRO motherboard?

I'm planning on getting a 9800GT video card for my system and it has 2 PCI Express 2.0 x16 slots. I'm wondering whether the double slot solution fits in my system on the first (blue) slot, since the southbridge heatsink may be in the way. Will it go past the southbridge, or will it get in the way so I'd have to stick with a single slot? Thanks.
Ok, this motherboard supports only Crossfire but not SLI, but I'm wondering if one double slot video card, as in ONE card taking up the space of two slots, will fit in the blue video card slot, since those cards have better heatsinks.

This motherboard only supports ATi's system of dual graphics cards (CrossFireX) and not nVidia's system of SLi.
