If you've already laid out the dough for a Sandy Bridge-E proc and an X79 motherboard, there's no point skimping on the RAM. Lots of memory is, without a doubt, a good thing; lots of speedy memory is a very good thing. G.Skill's Ripjaws line of high performance RAM has a long history of pushing DDR3 to its limits, and the company continued the proud tradition at the CeBIT exhibition in Germany, where G.Skill showed off what it calls "the fastest quad channel memory" around.
