Doom 3 should be out in march 2004, so it's still a while away. If you can wait that would be the best. By that time you should be able to get a 9700np around $160, maybe even a 9800np for that price. If you don't want to wait I think it still comes down to how much you want AA and AF. Look at some benchmarks. You can see that the ti4600 has more raw power with it off, but when on it falls behind.
Edit: Also link to benckmark anandtech did of 9 cards with doom 3. Too bad they didn't include a 4600 in this, but you can at least see what kind of performance you might get in the game with a 9600 pro. Though things can change quite a bit before a game's release.
