Izotope Insight Meters

Hey guys, was thinking of getting the RX3 bundle but the Advanced bundle has the Insight Meters included. I'll be running a mac mini 2.3 quad core i7 and ssd with typical reality show size mix sessions. You think the Insight Meters will suck up to much cpu for my modest sized setup? Haven't gotten my mini yet so it's hard to test out what my limits are. Maybe I can find cheaper, just as good meters? Thanks for any insight.
