Hi All, This is probably going to sound like a dumb question, but I figured I would ask. Being that you can switch the graphics card in the mac, will switching the card around a lot be detrimental to system? What I mean is, lets say I switch the graphics card nightly, for gaming, then back to normal will that affect the system adversely or is it designed for that. Sorry for possibly the noob question, but this is my first laptop of any kind that offers that option. Thanks for any help!
