Haswell E 5820K with PCI E lanes reduced to 28, Concern much?

I believe most of users trying to purchase Haswell E will choose 5820K. Anyway, 28 lanes for the Pci E will concern much if I would only like to a single graphic card?
Anyway looking forward to the performance of it wishing at least 30% upgrade to Ivy Bridge E.

    The maximum amount of lanes a single graphics card uses is 16, so it's fine.

    EDIT: There are generally chips on the motherboard that will allow for say, 8/8/8/8 for 4 GPUs even if the CPU only has say, 24 lanes. I could be wrong, but I think that's how it works.
