System seems pretty good though the AMD CPU is ashame but it's more than enough to play 720p video anyway. Xpress1250 video, it's up to you I guess. If it has component output I can say that component output from ATi cards is pretty good in HD resolutions, though they can only do up to 1080i via component. However that's not an issue for you anyway as the TV isn't that high res to begin with.
I've used the Xpress1250 before on an Abit board and wasn't impressed with the 2D image quality at all--in fact I thought it was quite poor by today's standards. However it may look better from your board or it may just look fine to you anyway, so I would just connect it via component and see what you think.
HDMI will look slightly better than component but it may not be worth the upgrade on your TV depending on how much that "HDMI board" you speak of costs. Anyway as I said, try the component out, see how it looks. If you're satisfied there probably isn't a big need to go HDMI.
