Video card choice for second P.C.

I've got a spare system with P4 2.0, 1gb, 80GB.
I'm not sure what video card to use.
My choices are:
ATI Radeon 9200 SE (128MB)
or
nVidia Geforce4 MX 420 (64MB)

I won't be playing any epic games on it. Just streaming movies from my main P.C. Then Second Life from time to time.

So /tech/, what video card should I use?

nVidia, they work better on Linux.
