David Short of IBM says that Windows Vista’s minimum requirement of 512 MB “really isn’t realistic.”

He says that users who wants to achieve optimum performance when using Microsoft’s latest operating system should have 4 GB of RAM on their PCs.

Short warned that those who have 512 MB should not install or use Vista since its performance will be “sub-XP.”

2 GB of RAM is the “sweet spot” in his opinion while a 4 GB of RAM would be “Nirvana.”

On Dell’s website, they mentioned that some of their Windows Vista compatible PCs are “Great for … Booting the Operating System, without running applications or games.”
