Members often say this.
They go on in circles chanting upgrade theology and touting expensive BTO specs like law. Don't listen to them. I can not believe the number of people on this board that insist - "first things first, gotta get dat RAM!" - without the slightest idea of what they're increasing it for and that, in fact, it will slow down the computer instead of increasing speed as the Mac has that much more RAM to process and account for.
Are you encoding hundreds of songs from FLAC to Apple Lossless on a daily basis, wherein your RAM is eaten up with every encode and you could use some more to avoid paging? Buy RAM.
If you throw a hissy fit because 8 is less than 16 and surely 16 is faster than 8, then you don't have any idea what you're talking about and you should stop pouring your insecurities into computer specifications.
OP, here's a quote from your previous thread on RAM upgrades:
These are the kind of members that I adoringly refer to above. Upgrading for the sake of upgrading is like getting a hair transplant with a full head of hair.
First off, Don't listen to this idiot.
More Ram doesn't make your computer run slower and it also doesn't make your computer run faster. It only helps if you run lots of applications or ram hungry applications. When you dont have extra ram and you system needs it, your computer will BOG down as it pages out to the Hard Drive as RAM.
I am not a power user, but I upgraded to 16 G, partly because is was cheap, but partly because my new cMBP only came with 4G (no way enough) and the jump from 8 to 16 was a small amount of cash.
Tonight I was running Parallels with WIn 7, had Outlook open for mail, and on this site with Safari and my system said I was using 7.5G of Ram.
Under the original 4G, yes, my computer would have slowed down as it used HD as ram. It probably would have worked with 8, but with 16, no issues.
If an extra $30 makes difference to you then get 8, but if you own a MBP, I doubt the $30 will make a difference, else, you would be on a $399 Asus or Samsung.
I bought 16 for $100 from OWC, and I believe that Amazon or Newegg has it even less. Remember when it was over a $1000!
That is why people usually recommend to upgrade to 16G because it is so cheap.
The only way to make your computer run FASTER is to upgrade the processor or over clock your current processor.
Good luck
