Unless you have a videocard with 16mb of ram which can get choppy for windows media player (and other such XP operations), there should be minimal difference in "speed" at which explorer opens (not demanding xp operation) and "smoothness" of scrolling on a webpage between graphics cards. You will be primarily limited by internet speed 1st, cpu speed 2nd and ram speed 3rd. Once you open a lot and get closer to 20, ram will become more critical than the cpu.
