Will a stronger Video card improve SONAR's overall performance?

Hi gang,

I've never had a need to mess with video cards in the past really - but I want to make a move to 4 monitors and I know a lot of open GUI windows can slow SONAR down.

My question is "what class of video cards will I need to get in order to have 4 monitors worth of stuff open - video window, track view, Kontakt, and a few VST effects - without hurting SONAR's performance and hopefully withour having a lot of fan noise in the control room?"

Thanks!
