No idea. Depends on what you use your computer for.
Page Ins vs Page Outs In addition to checking out the memory pie chart, look at your Page ins vs Page outs. If you have a high number of Page outs to Page ins, you probably need more RAM. I always just do a quick calculation, if Page outs are 10% or more of Page ins with regular computer use, I recommend a memory upgrade. In the screenshot above, Page outs represent 17% of Page ins. This user would benefit from more available system memory.
You may recall that paging is the Mac virtual memory system, which essentially uses your hard drive as virtual RAM when the real thing runs out. Virtual memory is a great feature, but its significantly slower than physical RAM, and a lot of page use will cause system slow downs.
Except the article is wrong. You will always have Page Ins, but you won't always have Page Outs, so any ratio between the two is irrelevant. You only need to look at Page Outs. Also, having Page Outs when doing something you infrequently do does not mean you will benefit from additional RAM. What matters is if you're paging out during regular use.This article will tell you if you need more RAM or not.
The brand is irrelevant. RAM is RAM, but price, warranty, etc. are factors to consider.If i decide to upgrade does it matter which make of RAM i use e.g. Crucial, Corsair ,etc
I know it uses DDR3 PC3-8500

Launch Activity Monitor and look at the System Memory tab at the bottom. If your "Page Outs" are zero under normal use, you're not maxing out the RAM that you have, and additional RAM will have no effect on performance. Be aware that the Page Outs are cumulative, since your last restart.

Hi, I noticed that the link showed that they were using Parallel?
Is this a good program to use?
....needs the 8GB though, struggled without it...
