I don't know of any specific issues you might have with that card, but in general: make sure your PSU can handle your card, make sure you have the latest chipset and AGP drivers installed (this depends on whatever chipset your motherboard has), make sure your card works perfectly with every game before trying to overclock it (I don't think you should overclock it, as your CPU will limit you more than the video card), and monitor the temps of the video card at all times, make sure they're much lower than 100C.
