The Asus XL looks nicer than most, and gives you dual DVI and VIVO. The Gigabyte is notable because it's fanless. Otherwise, I'm guessing they're all the same, quality-wise, and most should offer component output cables for an HDTV. I don't think the XL core overclocks that well, so I wouldn't expect much there. Just get one with a good warranty (three years, IMO) and the features you want.
