SLI & CFX PCIe Bandwidth Perf. - x16/x16 vs. x16/x8

@ 2010/08/16
Have you wanted to space your SLI or CFX video cards farther apart on your motherboard to allow for better airflow? Do you have a motherboard that will not support a x16/x16 PCIe configuration? We put x16/x16 and x16/x8 PCIe SLI and CFX configurations head to head and show you what sacrifice there is to be made.

You can find slight framerate differences between x16/x16 and x16/x8 SLI and CrossFireX video card configurations if you go looking for them while pushing games to super high end resolutions and quality settings, but nothing that negatively impacts a real world gaming experience. If you are wanting to use SLI or CrossFireX on that motherboard that does not support x16/x16 PCIe lanes, have no fear.
PCI 2.0 x8 is all we need
