Noob question regarding Gigabyte GA-Z68XP-UD3 running SLI/Crossfire

So I'm looking to buy a new computer, and have been checking out the aforementioned mobo ( 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?
