I have asked this before and never got a ansew, I dont know if it sounds completly silly and makes me look like an idiot or if it has a point. When you add a graphics card like a ati card does it share the power or memory of the onboard chip in anyway or do you just have to completly disable this? The reason I started this was because there are people on the net saying you do use the onboard graphics memory on top of the cards... confused now..
