Is it possible to rig up crossfire on a board that only has one PCI express x16 slot? Is there an extension card that I can buy that will have this?


I have an 880GM
-E35

Second question.

I have a Phenom II x3 720 BE
I also have an ATI 4890

Would like to buy another 4890 and crossfire.

Is this viable, will an AMD 970 handle this, and will an Earthwatts 650 Watt PSU run it?


Thanks
