I would disagree strongly with that. Even playing 1080i HD mpeg2 my X2 
3800 uses around only 30% usage without xvmc or vdpau. Marginal is a 
very strong term to use for that. I would more put it "has a huge 
comfort zone margin". I don't know anything about how it handles h.264 
though. I've been using this for a couple years now and don't see myself 
getting rid of it for quite a while since right now it can handle the 
highest bitrate OTA (and digital cable) I can find.
