Just out of curiosity. I thought I'd never hit above 80% on 8GB of RAM. But I was wrong... It happened a couple times. I've hit that mark when I have firefox, chrome, Adobe Illustrator, Adobe Photoshop, Adobe Audition, FL Studio, litecoin-qt, and Outlook (all above 100,000 K) open. If I attempt to open a game, I can imagine it hitting the >90% mark. Looks like I need more RAM.
Note, if you have more than 8GB of RAM (i.e. 16GB), then divide 8GB by 16GB [or the amount of RAM you have] and multiply it by 80%. So the question for 16GB users would be at 40% instead.
