the crucial ballistix tracers are good since they are double sided, while the normals ones have changed to single sided. but ur better of going with gskill, they have great prices and there ram is awesome for overclocking. NQ's are a great cheap set with good overclocking. with ocz, platnium is the best set there i think, but they are not as good for overclocking and gskill Nq's but if they are cheaper then i guess you could settle for them. im not really sure about the gold and the SLi is probably a waste becuase sli ready ram means nothing.
