MARKERS, How to improve display ?


I don’t have a fancy video game Graphic Card but it"‘s not the basic one from my MB it’s a AMD radeon HD6800 and i use 3 screens.
On some sessions if i have a lot of markers, for example when i import 3 or 4 EDL tracks from editor for a 52’ movie
then display becomes very slow ! 1 sec each time i move something on the screen ! i have to put them in a folder and hide it, only use one marker track at a time.
Would it make a difference if i buy a better graphic card ? what criteria should i look for ?
