Which Motherboard Should I Get for Phenom 9950

I am upgrading my PC. I Just bought an AMD Phenom X4 9950 Black Edition CPU and Corsair Dominator PC2-8500, 1066Mhz Memory - 2GB - I already have a EVGA 8800 GTS 640MB Video Card, But i plan on buying a second card and running them in SLI mode. I also have a 550W Antec Neo HE550 Power supply...will this be enough?

My main question is What Motherboard should I buy so that i can later run 2 8800 gts 640MB cards..in SLI mode..

Note: the 9950 is a 140w processor, so not all Phenom compatible boards will work correctly...

  1. Under $150 SLI at 8x/8x, good reviews, will handle the 9950

    The 550w Antec will handle the 8800GTS 640 in SLI.
  2. It's going to be cheaper and faster to sell the 8800GTS and get a newer card. The cheapest 8800GTS 640MB I could find was for $100 if you add to that the price of a SLI-capable board ($150) versus the price for a 790GX+SB750 board ($100), that should overclock a hell of a lot better... since it has an SB750, and an HD 4850 ($170), you will see that the difference in price is negligible, but the single HD 4850 should be faster, especially with AA enabled.

    And if you sell your 8800GTS 640MB on ebay, you can even make up some money back.

    If you still want to go with an SLI board though then get something like this

    MSI K9N2 SLI Platinum

  4. i think you shoud consider AMD 790fx + SB 750 it will make your phenom oc realy well, and your phenom can be oc to 3,4 gighertz preaty easy.

    and you should sell your 8800 gts, then buy 1 GB HD 4870 it will beat your 8800 gts even in SLI.
