So I think i'm going to go for the Sapphire Radeon 9600. It's selling at newegg.com for $95.50. But then I looked at the performance jump from the 9600 to the 9600 pro for only 35 dollars more. But then I noticed rumors that the even newer 9600 XT comes with a coupon for Half-Life 2 for FREE! (but the card costs about 40 bucks more than the pro).

My info on the specs etc comes from a couple of reviews from Tom's Hardware (I hate the ads, but the reviews are usually pretty solid). About the 9600 series and 9600XT vs 9600Pro

So I think the conclusion I'm heading toward is the 9600 because it's cheaper and has no fan, so it won't create cacophony in my computer. Then again, for 75 bucks more I get a pretty big jump in performance AND free halflife 2 (when it comes out) (which could be years from now).
