actually that mobo is set up for Triple Channel...happyrock, that article was dealing with 2GB vs. 4GB. What we are dealing with here is up to 8GB of very fast RAM (the G.Skill RAM comes in 2x2GB kits and although the motherboard has 6 RAM slots, only 4 can be utilized to keep the RAM running in dual channel mode), or up to 24GB of slower RAM (the 3x4GB kits rshaffer61 mentioned which carry huge price tags). If the OP is looking for maximum performance, it is almost certain that the 8GB of faster RAM will give him this over the 24GB of slower RAM, especially if he will be overclocking since the faster RAM will give him more headroom to do so.
