I'm building a combined mining/gaming rig for my father.  I'll be using a Radeon HD 6950 as the primary video card (for its gaming performance, of course), and two HD 5830s for cheap hashing power.  Presumably when he's firing up a game he'll pause the mining on the 6950 and then resume it when he's done.  Oh, and the OS will be Windows 7 64 bit.

The PSU I'm thinking of is a 950 W one by PC Power & Cooling: http://www.newegg.com/Product/Product.aspx?Item=N82E16817703028
And the motherboard has 3x PCI 16x slots:  http://www.newegg.com/Product/Product.aspx?Item=N82E16813157207

The rest of the system isn't really as relevant for mining purposes, but will include a hard drive, an optical drive, a pretty good AMD processor, and 8 GiB RAM.

So, the main question is, assuming I stick it all in a case with enough fans, is the PSU going to be sufficient to power those three video cards along with everything else?  Is the motherboard going to take it?  Can Windows 7 handle this?  Is there anything I haven't considered that I should think about?  (Dummy plugs?)

Thanks guys!

ASROCK mobo is AWESOME! Onboard on/off switch with LED clock info and a flash bios reset outside the mobo! (rear panel)
the mobo supports 3 pci-e slots, as long as you keep the cards cool your good. Look into the wattage for the cards (i think(

I knwo the 5830 each take up ~170 watt Im nto sure about the 6950 should be weaker. I think 950w shoudl be sufficient, just add all the wattage together and keep about ~100-150 gap so you dont break your PSU.

actually it'd be better if you just got 5830s instead of that 1 6-series card.

The 5830 could play many graphic intense games by itself (SCII Ultra albeit unstable FPS still high), with xfire you'd be able to play many games smoothly. For the price you might be able to do 3/4-xfire gaming rig if you will the trouble to 'un'-xfire them when u do mining. Just a thought. (I mean they're like a hundred bux a piece)

The total hashing rate (esp after OC) and power consumption would probably justify itself.

The pcie slots look very well spaced... I think it should work well.
