G.Skill still has faster and far better quality kits, unless I missed something? Corsair is too apple for my liking: all about about paying a premium for the name but with mediocre quality. I feel that a few other brands have better offerings.
G.Skill tops out at 3200MHz for SODIMM vs these at 4000MHz, also G.Skill are not great with warranty claims, weeks of arsing about - Corsair will replace faulty items within days with no quibbling involved.
