you could use both screens but only if the new computor has enough ports for pluging it in. this would work for only basic work programs you probably could not do any gaming with the dual screens. you probably cant or would want to use any of the old parts though.
The Comptuter has 3 monitor Outputs, they are going into my monitors. But what im am trying to do is connect 2 comptuters and it just so happens that a have 2 monitors.
the title is a bit cut off, sorry
