Video Card Recomendations

[unwritten_law9]

I'm currently running iDeneb v1.2 10.5.6 on my desktop. I got no sound and low resolution video. For video I have onboard ATI Radeon HD 3200, and sound I have onboard Realtek ALC889A. From what I have read I'm screwed for graphics, so i'm looking for a low end graphics card that will work flawlessly with OSX. Also suggestions on audio would help as well.

Here's my specs:
