I am wanting to start my system from scratch and make it a dual or even triple boot system. I have a problem deciding whether I should get Win XP Pro 32bit or 64bit. Is there a difference in available gaming power? The other question is, Is it worth it to get Vista yet? if so what version? Also I'm thinking about messing around with Linux a bit and Ubuntu will be my start platform, or is there something better out there? I've searched and I think Ubuntu will be the most user friendly. Help is much appreciated!
