So I'm looking to buy a new computer, and have been checking out the aforementioned mobo (http://www.gigabyte.us/products/product-page.aspx?pid=3892#ov). I want to have the capacity to run in SLI/crossfire further down the track, which is supported. However, I've been reading that when using two GPUs the 2 x16 PCIe slots will drop from x16 speeds down to x8. Is this something i should be concerned about?

Not really there about a 4% difference between x16 and x8 lanes with two cards.
