Thanks a ton guys for your explanation. So it sounds like 512 is plenty, even for that high a resolution. And no, I probably wouldn't play most games at that resolution, as some of the ones I play probably don't even go that high

This seems like a really silly question (and it's related to one I've asked on this board before), but what should I be looking at to also make sure I have optimum full-screen flash video playback? I would have thought my current setup would be enough for that, but if I play any flash video from ANY site, and make it full-screen, my PC starts whirring up and the video is still super low framerate (like 1fps). It seems weird to be building a computer with flash video in mind, but as that's only one thing I'm thinking about, I don't feel quite as weird about it
