Do EVGA motherboards support crossfire?

Nope.

That one your linking there doesn't, but their new boards - at least most of the x58's - are starting to support it.

Their X58 does, and that's about it. They deal in Nvidia chipsets, which only support SLI. However, you do not need a crossfire board to run a dual GPU card like the 4870x2. Dual GPU cards are like crossfire/SLI on a stick, it's built-in. But unless you already have this board, I'd just get a board with a nice Intel chipset that supports crossfire so that you can crossfire your 4870x2 with something else later on down the line.

Yeah I was just wondering about that board but I didnt think it supported it. I'm not buying i7 so I need to find a good x48mobo.

Anyone have any links to some good boards? I have been looking at a DFI but I do like Gigabyte.
