I'd go with the refurb X800XL with 1 year warranty. Mine is fine and came with the complete retail bundle. http://shop.ati.com/product.asp?sku=2984012
If you simply must have new, the AIW X800XT is a more powerful gaming card, plus it has a TV tuner card, remote control, and video inputs, and some extra software. Good deal unless you wanted to add an aftermarket cooler and push extreme overclocks. http://shop.ati.com/product.asp?sku=2588471
Anyway, the 9800 pro is holding you back bigtime on that nice rig; either of these cards would be a huge upgrade.
