I am getting a New Dell system with Core 2 Quad Processor. It comes with Vista Home Premium but many of my software will not be supported by Vista so I am thinking about installing Win XP Pro SP2 OS when I get the system. But I am not sure if XP will support Core 2 Quad Processor or not. Anyone knows the answer or alternate solution ? I really like that system & I need the as much processing power as possible. My applications are very processor intensive so more the better. Thanks in advance.
