Comparing Nvidia GeForce 9100 to Radeon HD 3650

[Filthyavian]

I just bought a computer (ya I shoulda built it, im too lazy) and it has a NVIDIA GeForce 9100 for the graphics card. Last year I had to upgrade my old machine and I went and bought a VisionTek Radeon HD 3650 that is currently installed. My question is, if I use my machine primarily for gaming, should I leave the GeForce 9100 in, or should I install the Radeon HD 3650 out of my old machine? Please help me out as I am a retard in these things. Thanks.

The 3650 should be a good bit faster. From what I have seen, it performs similarly to the nvidia 8600gt.
