Ok so proud owner of an i7 iMac, refresh coming, I don't care coz I'm in love (screen fine touch wood). Snow Leopard is presently lounging about in the giddy excess of 8GB ram. I'm wondering, while it's nice to know I could go to 16GB, in what instance would I actually want to? I know more ram means you can have more apps open simultaneously, but it's fairly rare for me to want to run Photoshop and Final Cut or or what have you at the same time. (Not unknown perhaps but rare.) Also, I run Parallels, and I have noticed that having 8GB to toss about (vs originally 4GB) does help a lot - I can afford to throw plenty of ram at Windows 7 and still have a functional and responsive OSX desktop. But other than those cases, what could the ram be used for? I presume for gaming once you are past 8GB there's no performance difference is there (under Windows or OSX)? Or do I not understand how these things work? Basically I'm looking for someone to tell me "Yeah 16GB, go for it, it'll feel like a new machine!" ?
