It depends. 32 bit color isn't really possible on a geforce 2 at that rez, no matter how much memory you throw at it, bandwidth is still too limited. You'd be able to play games that aren't fps intensive at 1600X1200, stuff like Vampire the Masquerade and possibly War Craft III. Quake III is also playable at that rez with all the newest patches, but few of the Quake III engine games will be fluid. (Alice, FAKK2, Star Trek Elite Force, etc.)
I'm running a classic Tbird 900, and I just upgraded to a gainward Geforce 3 from a classic GTS like you have, and while it's nice, I'd have liked to wait until April for a Geforce 4 or whatever if I didn't need a card stat because the GTS went bad and killed my monitor.

While some games are CPU limited for me, when that happens, you basically get FSAA for free as it won't cost you FPS that you're not getting to begin with. Max Payne is like that, it really would like a faster CPU.
I've just been fooling around with Giants: Citizen K and both 1600X1200 32 bit, 32 tap a-filtering and 1024X768 32 bit, 32 tap a-filtering Quincunx FSAA are fluid
. While the latter gets rid of quite a bit of jaggies, the few that it doesn't get rid of are THAT much more annoying and the textures on the 1600X1200 are sharp as hell, so it really comes down to personal opinion. On the otherhand, 1600X1200 can make a lot of games really sterile looking, and playing at lower rez where things blur a little bit can feel more immersive.
As always, your milage may vary.
