This is a quote from the Bit Tech article you referenced:
If you're the type of person that runs dozens of applications all at once, then a higher memory frequency does help, particularly when you're running demanding software. However, our testing shows that memory rated at over 1,866MHz doesn't give much extra performance. Worse still, in some applications only 1,333MHz memory gives a performance penalty, meaning that 1,600MHz memory is fine.
If you're doing anything other than heavy multi-tasking - this goes for gamers in particular - then a 1,600MHz or 1,866MHz kit is plenty. You could opt for CL8, as we saw some advantage in the video encoding test, but we wouldn't obsess over this factor, especially if a CL9 kit is much cheaper.
Obviously this backs up what you are saying. However, if you are only doing occasional video encoding or extreme multitasking then I don't think you will notice the difference. And seeing as how the ECO RAM is $179 (CAS 8 1.35V) I doubt it is worth it compared to something like the GSkill Snipers considering they are CAS 9 at 1600 (1.5v) and can overclock easily to 1866. And even that article concludes you won't see much a difference beyond CAS 9 and 1866.
