Dell Dimension 4550 Video Card Compatibility?

I have a Dell Dimension 4550. I was wondering if a nVIDIA GeForce FX 5500 256 MB AGP video card is compatible with it.|||The nVidia GeForce FX5500 is fully compatible with your system(which accepts 1.5v agp 2x/4x)-(the video card should have the connector divided into three parts.)
