With Windows Vista coming soon to a retail channel near you, one of the important questions to ask is, "How much memory does it really need?" There are the official minimum requirements of 512 MB, but we all know that minimum requirements don't translate to a great experience. What are the real memory levels that get good performance? After having used it for several years during the development process, I figure I'm in a pretty good place to help answer that question. Vista definitely requires more memory than XP did to achieve similar levels of performance. That is to be expected with all of the new functionality invovled. To run Vista at its best, I recommend you have at least 1.5 gigabytes of RAM. In my experience, the following is a mapping from XP RAM to Vista RAM requirements for eqivlaent performance.
XP RAM Vista RAM 128 MB 512 MB 256 MB 1 GB 512 MB 1.5 GB 1 GB 2 GBBink: I agree, run full blown Vista, you'll need at least 1,5 Gb

If you're running x64 you might as well have more memory anyways, like 4GB or more, simply because x64 can use it better. This is, though, specific to the types of apps you use, and if they get a boost on x64 or not.
Lots of new PCs sold come with 1GB now, and even many laptops are sold with 2GB, RAM memory is moving higher just like HDDs have, and the new DDR3 spec should help push DDR2 prices lower, i'd hope.
