Newbiw with Saitek / multi onitor questions

First post, happy to have found this forum.

Been an aviation enthusiast for years and having only just discovered that home cockpits actually exist, I have jumped straight in an ordered a high-spec 3-monitor ready pc to enable me to learn and have fun on FSX.

I've done tons of research and whilst attracted to all the Saitek gear, from your experience, would it be better to have a separate 4th screen for instruments or 6-pack Saitek one? Big difference in cost of course, but would my 8 meg ram / Intel i5 4.over-clocked 4ghz quad core muvbd / 2gb GTX 770 video card setup be able to run 4 screens (setting it up would be another issue...)?

Thanks for listening.
