I am probably going to migrate my work laptop (WinXP, ThinkPad T61) to Windows7 soon, and want to take the opportunity to upgrade to a 64bit OS and use the infinite amounts of RAM this will allow :)
Given that laptop RAM not free, how much RAM would actually make a difference to my normal dev environment - VisualStudio running in a couple of instances, Firefox with umpty tabs open, perhaps one or two other apps running as well? Will I see much difference in upgrading from 32bit XP and 2GB RAM, and if so where is the cut off point? Is 4GB enough, or will I see a noticeable improvement with 6 or 8 or whatever... Thanks!
