<div>That may be. I also am driving my screen at 1024x768 using a VGA to NTSC converter playing HD scaled down to that resolution. I feel I'm at the very edge of what I can do on this processor as not using XvMC studders. I have a feeling that if I ever go to an HDTV, I'm going to factor in an upgrade to a CPU that can simply just chew through HD.</div>
