Yes, and suppose we only want a video card and not muck with finding a new motherboard with the PCI-E interfaces?
Personally, I can't give much advice. My newest-gen card is a Geforce4 Ti4400, so I'm not too knowledgable on how the newest of the new perform. I've heard much good about the current crop of Radeons, and some not-entirely-unearned ribbing of the FX series. If you ask me, the 9600XT might be the best choice if you want a balance of power and price.
Now, going on a minor tangent from this, I've done a bit of reading on the All-in-wonder Radeons, and from what I gather they're effectively a slightly refined 9x00 with an integrated TV/FM tuner and appropriate signal processors. Granted, they only run 128mb of memory, but that's plenty enough for the crop of software I'm using. And since I'm also needing a TV tuner in my system (as the dorms back at uni are notoroiously lacking in both space and power taps) I figure this would serve well as a replacement for my aging Geforce4. But, naturally, I've heard rumors that the AIWs are generally a bad thing when it comes to TV viewing (a contradiction from what Anandtech's review of the AIW 9600 Pro says).
Opinions?
