Solved Multi graphics cards in 8x pcie slots Tags: Graphics Cards Motherboards Graphics Last response: June 29, 2011 5:46 PM in Graphics & Displays Share boeing114 June 29, 2011 5:40:33 PM I see a lot of motherboards will offer 2 pcie 2.0 slots, and if you use one of them, it will give you a 16x lane, but if you use both of them (hence sli or crossfire), you only get 8x lanes. Does this hamper performance?
