While DDR3 is making its way to the Intel platform at record pace, DDR2 simply won't die anytime soon, why is this? AMD still have its foot in the door on this technology, and due to its integrated memory controller on its CPU line, it's hard to change memory standards without re-designing the CPU and motherboard. Intel however can go either way, but again this has its drawbacks too.
G.Skill's kits were very impressive, especially their DDR3 kit. Speeds are now starting to approach the 2000 MHz barrier, some have broken this already in fact, and it won't be long before all makers do. With higher yields coming expect DDR3 to launch high very soon.
