Howdy Creeky and welcome to the forums!

yes, keyclone will coordinate your characters on both machines.

i would ask though... if you are going to have a quad core, why not just have a single machine with 2 monitors? that way, you would be able to pip swap screens if necessary.

also.. if you are going to order a new machine.. i would recommend the nvidia 8800 series. definitely a quality card (although i have heard the 9800s are out...)

if you have any questions, please feel free to drop me a note.

have a great day ... and welcome to our addiction
