    Default PCIe 8x enough for RadeonHD 3870?

    I was thinking of setting up dedicated GPU for virtual machine but it appears doing this would drop the bus from 16x to 8x. Would this have a bad impact on performance if the better of the cards is RadeonHD 3870?

    Performance hit should be less than 5% for the 3870.
