looking for a PCI video card for the ex-wife's PC

My ex-wife has an old HP pavilion 515n

It is currently running with on board video. I think its at 64megs, not sure.

There is no AGP slot. Only an extra PCI slot available. ( NOT pci express )

I believe it runs on a 200w power supply (FSP200-60SPV-D)

My son, whom lives with his mother, likes to play games like WoW and Never Winter Nights.

I am looking to purchase a PCI video card that has at least 128/256 megs of Ram and support for pixel shader 2.0. I would also like to use an Nvidia brand (just personal preference)

I've already checked Newegg and found many cards under $60.00 with enough ram but none list the shader support. Is there a way to find out if any of these cards support shader 2.0? or could someone point me in the direction of a good PCI card that doesn't cost to much?

Any help?

Easy,The FX series is 2.0, Nvidia 6 series and up support PS 3.0

she's the ex, tell her to get it for her self, plus getting a pci card is a mistake as the guy above said get a cheap motherboard and processor with on board gfx card it would work out about the same price
