I have this motherboard.. http://www.newegg.com/Product/Product.aspx?Item=N82E168... ...and was wondering if it would run 2 Asus GTX 590's or 2 EVGA Gtx 590's in Quad SLI.The item details just say SLI.It has 2 PCIe X16 slots.If not then I'll just go with 2 of these...http://www.newegg.com/Product/Product.aspx?Item=N82E168.......

Probably, but I couldn't guarantee it.

That motherboard has very poor spacing between the PCI-E x16 slots. The double slot-width video cards would be close together with one of the cards having poor air flow.

I have 2 GTS 450's in SLI but was hoping that Quad SLI works on this board.

From NVIDIA's "How to Build a Quad SLI Gaming Rig" guide :

Motherboard
GeForce GTX 590 in a Quad SLI configuration requires a SLI-certified motherboard with an extra PCIE slot between the two double-width cards to ensure both receive enough cooling air. If you're water cooling the cards, you can get by without this extra slot, but for air-based cooling it is a necessity.

The clear air between the two GeForce GTX 590 graphics cards ensures that thermal performance remains within acceptable limits.

Quad SLI certified motherboards that have the correct connector spacing for use with dual GTX 590s are as follows :
  • ASUS Maximus III Extreme
  • ASUS P6T7 WS Supercomputer
  • ASUS P8P67 Deluxe
  • ASUS P8P67 Pro
  • ASUS P8P67 WS Revolution
  • ASUS Rampage III Extreme
  • ASUS Rampage III Formula
  • ASUS Sabertooth P67
  • DFI LanParty_DK_P55_T3EH9
  • EVGA P55 E658
  • EVGA X58 FTW3
  • Gigabyte GA-EX58-Extreme
  • Gigabyte GA-P55-UD5
  • Gigabyte GA-P67A-UD5
  • Gigabyte GA-P67A-UD7
  • Gigabyte GA-X58A-UD7
  • Gigabyte GA-X58A-UD9
  • MSI P67A-GD65
  • MSI X58 Pro-E

    CPU
    With the combined power of four GTX 500 GPUs, Quad SLI can be easily bottlenecked by the central processor. Therefore, it's important in this case to have a fast CPU to get maximum performance. Core i7 CPUs with Turbo Mode enabled are highly recommended, and for even better performance, you may even want to consider overclocking your processor.

    Power Supply
    Operating a Quad SLI GTX 590 system requires a power supply that has four 8-pin PCI-Express supplementary power connectors, each of which must receive 150 Watts. Because of the complexity of designing, building and ensuring that the power supply meets these necessary requirements, NVIDIA works directly with power supply manufacturers to certify their products for Quad SLI use. The list of power supplies certified for use with a Quad SLI GTX 590 configuration is as follows :
  • AcBel PC8055-000G 1100W
  • Antec HCP-1200
  • Corsair AX1200
  • Nexus RX-1.1K Gold
  • Silverstone ST1500
  • Thermaltake Toughpower W0171 1500

    Chassis
    A good computer case provides the proper airflow for cooling the graphics cards, without sounding like a jet engine. The optimal chassis has multiple fans that draw in cool air and push out hot air, with a large fan positioned on the door side panel to blow cool air over the graphics cards. The case must also support 11 inch graphics cards. As with the power supplies, NVIDIA works with manufacturers to ensure that their cases are certified for use with Quad SLI configurations, and as of today the list of certified cases is as follows :
  • Coolermaster HAF X
  • Silverstone Raven RV02
  • Thermaltake Element V

    Watercooling
    While the right case and air-cooling setup can result in low temperatures in a Quad SLI PC, water cooling can take thermal performance to the next level, resulting in an even cooler, quieter system that can be heavily overclocked. We've worked with several of the top water cooling companies in the world to build custom water blocks for the GeForce GTX 590, including :
  • EK
  • DangerDen
  • Coolit

    System RAM / Operating System
    For the best performance possible in a Quad SLI configuration, 6GB of system memory is highly recommended, and because of this the use of a 64-bit operating system is required. Windows 7 64-bit is recommended, though Windows Vista 64-bit will also suffice.
