Best video card for The Sims! (2D vs 3D)

Hello

Someone I know has a Dell with the following specs

Pentium III 866Mhz
i815 Intel/Dell motherboard
Geforce2 GTS 32MB (Dell) (latest drivers)
Sound Blaster Live! value
Windows XP

She likes to play The Sims!, and wants it to run a little smoother. I was
thinking of trading her my Radeon VE 64MB sgram card, thinking that
the Radeon VE would have better 2D performance, therefore making The Sims!
games play smoother. I know the Geforce2 will have better 3D performance
and hardware T&L, but doesn't the Radeon have better 2D performance? And
doesn't The Sims! rely more on 2D performance?

Or, better yet, if she wants to spend a few bucks, I was thinking of
replacing the existing GForce2 with either a GForce4 TI 4200 64MB, or a
GeForce FX 5200 64MB. I know the *4 TI 4200 benchmarks higher than the FX
5200. But the *FX 5200 is cheaper, and is supposed to be able to take
better advantage of DirectX 9.0 optimizations, which may give it a higher
benchmark in future games.

Thanks in advance for any advice
Ed
