I'm looking into a new system but before I do there's some confusion I have about 64bit technology and compatability. Can you have a 64bit processor operate a 32bit OS (Windows XP)? Can a 64bit OS operate using a 32bit processor? Is Windows Vista going to be a 32bit or 64bit OS? Is the new Intel Conroe processors 64bit processors? Are games and apps dependent on whether or not you have a 64/32bit OS/Processor? For example if I have both a 64 OS and Processor will I be able to run all my games I still have? I've heard a lot of the new 64bit processors are backwards compatible with 32bit OS's. How would I know if this was true? Is the Conroe backwards compatible?
