I know that there are close to 78 threads on macbook memory. Forgive me for having to start 79. Please keep reading though. Thanks. I have noticed (as many people have pointed out) that newegg. com is selling g skill ram for $79/ 1gb memory stick. All of the reviews on newegg.com look to be positive but I have read on these threads a few negative things about g. skill. I am trying to decide between the cheaper g. skill 2 gb ($160) or the http://www.datamem.com or OWC. The later two cost about $50 more. Is there really a difference. For some reason I would feel better spending more on the more expensive ram. Is it a false sense of security. They both seem to be good ram. Will OWC or datamem last longer than g. skill? I'm just surprised by the large price difference if they are practically the same thing. Alright thanks for the help and I'm sorry for having to post another thread like this.
