Service Pack 1 or 2 should always come first, even if the chipset drivers don't insist.
DirectX should usually come next as chipset drivers often ask for these, and most video card drivers do.
Chipset drivers are next.
Next, take care of miscellaneous, but important motherboard drivers. Hard drive controllers (which you'll need for a board with SATA and/or RAID functions), USB, and anything along those lines.
Video card should come next.
Any other drivers for the motherboard or any sort of attached cards (e.g. PCI sound card) should come next.
Everything else can come next.
