It all depends on your TV Matt. I've got a Samsung - I forget the exact model - and the 360 via HDMI looks awful, yet via a VGA cable it's pin-sharp.
Unfortunately there's not a lot you can do to find out what it will be like short of buying the cable and taking it back if it looks crap.
Really? Got my Elite hooked up via HDMI to my new 46" Samsung and it looks amazing...
