There are a few motherboards that I am going to choose from to build for my first gaming rig but I have a question. Since a SLI setup requires 2 PCIe ports, on the filtering sidebar, it has a choice of 1,2 PCIe ports etc, and SLI, Crossfire, etc. Would any motherboard with 2 PCIe ports be SLI compatible or do I have to buy one that supports SLI because the selections with the 2 PCIe ports are less expensive than the ones in the SLI category.
