If you're running Windows 2000, nV may offer better multi-mon options than ATi (namely, independent resolutions--both offer that feature in XP, though). Most new cards offer dual-CRT outputs, though be sure the card you buy includes a DVI-CRT adapter (some OEM models skimp on this, which you'll have to buy separately for $10+).
If you're not interested in 3D performance at all, consider a card without a fan (just a heatsink) to eliminate a potential source of noise or failure. I'd look into a Radeon 7x00 or 9000, or GF4MX or 5200. I'd avoid a GF4Ti or earlier for 2D quality.
If by performance you mean 3D gaming, then look into a 9600 Pro at a minimum. You'd do best with a ~$200 9800 or 5900, obviously.
A GF4Ti 4200 is still a decent card for 3D speed, but I'm not sure it's shaken its reputation for uneven 2D quality. It's also getting a little long in the tooth, but a $100 128MB 4200 should compare favorably to a 9600P in terms of price/performance in plain rendering. (Keep in mind the 9600P will offer better 2D and DVD quality, AF & AA speed, and DX9 compliance.)
