I will be a hardcore PC guy gone mac soon. I am getting a mac pro in a few days. On my PC I run a dell 30'' and a sony XBR3 at 1080P on an 8800gt. It works well. The one thing that could ruin my mac switching plans is my TV giving me problems. I will have an ATI and nvidia card on hand for the MAC pro. Will have any trouble getting this to work well? Meaning being able to run native 1080P and adjust for overscan/underscan if I need to. Nvidia and ati vista drivers allow for all of this. I have heard the mac drivers are not very robust.
