I'd have to second a Quadro FX (Not NVS.)
There's many reasons, but they put out a solid framerate, which is necessary when recording 3D animation.
Also, my FX2500 plays WOW better than any gaming card I've yet tried comparitive settings. Full detail, 1600x1200 - solid 50+fps (on a Dell M90 laptop no less).
I remember ATI does have their FireGL or FirePro lines that are supposed to be comparable, though I've never used one... http://www.newegg.com/Product/Product.aspx?Item=N82E16814195098&Tpk=firepro%20v7800
of course, that'd be if money were no object... However, other itterations of each brand, FireGL / FirePro or Quadro still do hold their own very well; I used to talk with someone close to nVidia, whom hinted that the Quadro-brand is the next step (or sometimes 2 steps ahead) of their GF-lineup.
A Quadro FX 770 should be in the $150-range and could do 3D fairly well.
