I've always assume there is a HUGE difference between dedicated and integrated graphics. Is there still one? I assume so. From my own experience, when I transitioned from a MacBook to a MacBookPro with the dedicated video card, and installed Windows (via bootcamp) it was the difference between night and day. I realize that dedicated cards now come with 1-2 or more GB of VRam. I assume if your machine has an integrated card, and you have 8GB of RAM, that conceivably your integrated graphic card could utilize 1 or more GB of you RAM. What else are they lacking as compared to a dedicated card that adversely impacts performance? Thanks!
