Help me pick a vid card for new system please

apple

Hey all, I'm looking to build a pretty nice comp for my family for xmas.  I have everything picked out except the video card.
I'm looking to spend around $150, and it needs to work good for Halo, BF1942, Dvds, and maybe Half Life 2.  Any suggestions?
Thanks,
-Chris

Its american... My christmas bonus wasn't as big as I had hoped, so I'm just going to give them my current card (GF4 MX440  )
I'll pick up a new card next month for myself.

Ati Radeon 9600
The Radeons work better than the Geforces for Halo anyway...
I am being biased however since I have a 9600 Pro 256MB   Great card though
