Help with system specs

[xTweaKy]

I have a NVIDIA GeForce4 420 Go 32M (this is what it says) graphics card, but that doesn't show up on the accepted graphics card list, but because it's BETTER (higher number) than some of the graphic card specs, I'm wondering if it will still work? I'm really worried about this, because I have 2 computers, one with ATI200x and then this one, and the ATI one kinda sucks, and I want to make sure the Sims 3 will work on at least one of my computers before I buy it. Thanks
