I have a mid-2010 15" MPB that is currently running snow leopard. I am very interested in updating to mountain lion but I'm a little apprehensive because I don't know if my mbp will run slow with it. I have a 2.66 GHz Intel Core i7 processor and 4GB RAM and use the computer for school work like writing papers, watching movies and going on the internet. So would I benefit from getting 4 more RAM? And, if I do, do I need to get an 8gb module or can I add a 4gb one to the second RAM holder? Also, will adding the RAM do anything to the data info on my computer? Thanks so much for the help!!!

My MBP from 2008 didn't see any performance difference between Lion and ML (or even SL and Lion). I highly doubt you'll see any difference either.

Your MBP likely will have 2x 2GB modules. For 8GB, you would want 2x 4GB.

As to whether or not you'll need more memory, launch Activity Monitor and look at the page outs value (see screenshot here). If it is significantly greater than zero, you can benefit from more RAM.

EDIT: Turns out Apple has instructions for testing this too.

Cool, thanks. My page out is 433.9 MB... is that low enough?

Really anything above zero could benefit. Currently mine is at 1.25GB after just two days of light use, so I know I could use more RAM (too bad my machine doesn't support more than 4GB - 6GB isn't worth it)

You should be fine with 4GB. Most people saw a slow down going to Lion from Snow Leopard, but Mountain Lion will speed you back up.

You practically don't do anything with your computer. You're not going to see any noticeable performance gain by adding ram.
