CF @ PCIE2.0 8x vs 16x Tags: Motherboards Performance Last response: September 15, 2008 9:02 PM in Motherboards Share Night-Stalker September 14, 2008 1:54:16 AM I was just wondering a CF 4870 on pcie2.0 8x links vs on pcie2.0 16xlinks, is there a performance gap? I own a P5Q deluxe and i am planning to get a 4870 and get another a bit later down the road.
