Microsoft inveiled today the BETA 2 for Windows Vista and released a tool on their Vista pages that you can use to ensure if your system will run Vista (hardware, software and drivers) and what will need to be changed if anything.
For those unsure or worried: My PC is four years old now with only my video card being newer and I am always updating drivers and my system passed.. so long as you update your drivers you should be fine imho.
