Tooling around on NewEgg, I discovered that I could dump 16gigs of RAM in my "aging" iMac for about 40USD, so I figured I'd go for it. I'm aware that "zomg 4gig only lolz" and "wtf 64bit n00b" seem to be prevailing sentiments when asking if one should use 64bit software or upgrading RAM past a certain point, so I hope to avoid that. My question is, basically, are there good uses for a RAMdisk under OS X? Back in days of yore (before hard drives), I used to use them in DOS to load up games and the OS and stuff, but I *hope* that, with so much memory, the OS should never need to be touched. I've been doing reading and learned that some people like to put their Minecraft data on a RAMdisk, and seen some benefit from that. Are there other scenarios (out side of manipulation of very large multimedia files) where I can make good use of the doubled RAM, either in general or in the form of a RAMdisk? What about under Bootcamp? At the moment, I have Win7's swapfile disabled, and never had an issue with it. Can I pimp some of that RAM into a swapfile? Thanks for your time and constructive input.
