Has anyone more than toyed with AMD's triple core processor? The little
bit of playtime in my local Fry's it seem faster that I thought it would
be using two large Photoshop files...

I do not know any windows video editing software, but presume that would
be quicker when making some edits to write a dvd, or VCD to send about
for family or friends...
