I just had open more than 20 apps (iTunes, iMovie, iPhoto, Pages, Keynote, Safari and Chrome with a lot of tabs open, GameCentre...that kind of thing) and I was using 5.5Gb. So that is another 2.5Gb of RAM I could use before it would then throw out all App Cache (which was 1Gb), then that is another 1Gb before the system would then start to compress RAM, where I would then have 4Gb before I started to Swap heavily to HDD. That totals up to me using around 40% of RAM (with 100% representing the point in which Swap takes place). Seeing as I usually only have one Application open at a time, 8Gb of RAM is more than enough for me, and I plan to keep my iMac for at least 5 years before I would buy another one (and I would not sell it, I'd keep it as a second monitor, or even just sit it somewhere nice) so resale never meant nothing to me either.
I can't say to what would suit you better, but hopefully my decision will help you with your own 🙂 If your like me, 8Gb is great! If you are running VM's though, go for 16Gb.
