If I ran two NVIDIA GTX 550 ti video cards, would type of motherboard and power supply should I get?

Question by Jesse J: If I ran two NVIDIA GTX 550 ti video cards, would type of motherboard and power supply should I get?
Would a standard 850 watt sli/crossfire ready power supply work with dual GTX 550 ti cards?
Would the following motherboard be a good choice for two gtx 550 video cards:
(3-Way SLI Support) Gigabyte X79-UD5 Intel X79 Chipset Quad Channel DDR3 ATX Mainboard w/ UEFI DualBIOS, Dolby Home Theater 7.1 Audio, GbLAN, USB3.0, SATA-III RAID, 3 Gen3 PCIe X16, 2 PCIe X1 & 1 PCI
Are there any other recommended specs for a computer with at least these hardware features? I plan to have at least 8gb of memory and a good sound blaster sound card as well, so that, coupled with a network card, would take the rest of my PCIe slots.
And so I don’t sound like a complete newbie, I do notice that these graphic cards, one of which I own already, takes up two PCIe slots. Does this mean that the above specified motherboard has too few slots to handle this, or did I do my calculations right?
Or is this a better bet:
(4-Way SLI Support) ASUS Rampage IV Extreme Intel X79 Chipset Quad Channel DDR3 ATX w/ ROG Connect, UEFI BIOS, BT GO, OC Key, Subzero Sense & 7.1 HD Audio, Intel GbLAN, USB3.0, SATA-III RAID, 5 Gen3 PCIe X16 & 1 PCIe X1

I only ask about whether or not dual would work with the first mother board spec’s because the video cards are in fact 16x. I’d figure that if they take up two slots, 3 PCIe 16x slots wouldn’t work. But I wanted to make sure I’m thinking about this right.

Answer by Ryun V
I wouldn’t really recommend SLI’ing two weak cards together.
A better option would be a single HD 7850 or GTX 560 Ti, so you’ll encounter less problems that come with SLI, and you’ll also use a lot less power. That way, you’ll be spending less on the power bills.

    you really need a mb with a minimum of at least 2 pcie slots, and the nvidia chipset, not ATI. i suggest the GTX590 OR BETTER.

    Yes, the Gigabyte X79-UD5 will support running two 550Ti video cards.
    You are way over “thinking” this. All you need is a motherboard that supports SLI. Yes, those cards take up 2 slots each, but the PCIeX16 slots are spaced accordingly.
    What socket 2011 processor are you using?
