What is the optimum percentage for RAM usage?

As low as possible... :D 

But anything from 10-70% is normal. Reached 100%, then you'll need upgrade.

Are you referring the RAM usage or the amount of RAM to be installed for the PC?

Can you start Task Manager (CTRL + SHIFT + ESC) and check for these values:

This means that you are using about 2,1 GB out of your 4 GB. Excluding that another 1,6 GB is used for caching.

It is no problem really, but it could seem a little to high with 2 GB used with just OS loaded and Firefox running.

You're all good...

Only suspect lack of RAM issue if you're having lag issues or temporary freezing, which means you don't have the proper amount of RAM in your system.

FYI, my 2GB on XP works like a charm. I assume a 4GB on the 7 will perform even better. ;)

So it seemed RAM capasity is more important than CPU Cache.
(in performance speed & less lack)
