Will GeForce 7600 GS work with Dimension 4600?

So basically I've determined that my old Radeon 9700 is dated and (especially to play new games like BioShock) unable to render good virtual shading effects, it being a 2.0 and new games requiring 3.0 pixel shader cards. Thus, I have settled upon a GeForce 7600 GS (512 MB RAM, ~600MHZ bus) for my AGP slot in my Dimension 4600 PC. Only, I want to make REALLY sure before I spend the money on the card: will a GeForce 7600 GS (NOT gT, specifically GS) work with my 4600?

 And as an afterthought, is there a specific brand I should look for? I was thinking of a PNY card...
