Multiple screens and gauges

i,
I am a 4 year use of FS in a limited way (ie difficult approaches and the like) and am used to 2D gauge displays which are easy to use on a separate screen. I am now the proud owner of a new and very powerful system with triple screens etc etc and am loving it but miss my easy to read gauges. My present system uses Vista 64 bit Premium and a high end card. the old one a single 3 mghz chip clocked to 3.3 which worked well for a 17" screen using Window XP home.
I am told that I can network the old and the new computers and run Project Magenta which will give me the gauges on their own screen (2D or 3D as the separate windows available when using the high end system with virtual cockpit. My aim is to achieve the 3 screen virtual cockpit I have now plus a moving map and flight plan on the fourth screen ( 2nd outlet of the main system card) and the second system networked to give me high def. gauges for easy navigation plus ? ( will it run a further screen from the second card outlet number two?
All options described would be very welcome and any advice you can think of

All help greatly appreciated and the simpler the better.

Regards

David
