Ok here is the deal I am in the USA so Newegg links are perfectly ok. I am building a new system on a ASUS Striker II Formula has the Nvidia 780i chipset.(http://www.newegg.com/Product/Product.aspx?Item=N82E16813131255). I want to use both of the PCI 1x slots on the board 1 for the sound card inclined and the other for an external raid. I do 3d graphics with 3ds max and Maya I also work with the adobe products. I am running air or water I have not decided for sure yet so either option is ok, but I am leaning towards air. The real problem is I am trying to find a graphics card 2 in SLI mode that will give me the ability to use both PCI 1x slots. to still game. crysis on high or highest setting with AA & AF enabled say 40 fps. And I need a little help. Trying to stay under $400

Thanks for listing to me
