Has there been any speculation on what the Intel Powermacs may include for a Video Card? Any speculation if you could just buy off the shelf PC video card and use those? Since intel Macs run windows now it would be great to finnaly get rid of my PC and have a Mac as a nice game rig. My intel Imac is great for games under windows but my PC still has better framerates due to the better video card. Anyone have any rumors or a good guess?
