Eh? According to what? I can run 800x600 and 1024x768 just fine to a TV over 
SVid or Composite using the nvidia driver. I'm pushing 1024x768 to a 27" TV

Since you said you have component inputs, rather than getting a new video 
card, I'd investigate a VGA to component video transcoder. That's what I use 
for my HDTV, and the picture blows away SVideo, especially for DVD and Divx.
