A few build questions

[Wrathfulram]

Hello, what AMD motherboard would support 2 Gigabyte Gtx 980's http://www.newegg.com/Product/Product.aspx?Item=N82E16814125682 in SLI with also a Gtx 780 dedicated to AA or PhysX? Is this even possible? 

 

My other parts are: 

 

AMD 8350 with H100i Water cooler

16GB Ram  

Seasonic 850W http://www.newegg.com/Product/Product.aspx?Item=N82E16817151102 Is this enough power for 2 980's and a 780? 

 

Thank you for your time.

Seasonic 850W - Is this enough power for 2 980's and a 780? 

 

 

 

Err, I don't think so...

[WoodenMarker]

Yes, that is possible.

Get any motherboard with the 990FX chipset...it provides the most amount of PCI-E lanes so that your all your cards can function correctly (Up to 32 lanes are provided)

 

Theoretically, the PSU is a bit undersized IF you calculate the maximum based on current carrying capacity of the components BUT in the link that woodenmarker provided, there is most likely a wall meter providing raw output. So you should be ok.
