well the best performing low profile ready (has a low profile bracket that you have to screw on) is the 9800 GT. It's 100 dollars and you can find it here
the 9800GT is a faster card, that's whats better about it. the 9500GT wouldn't get you anywhere gaming wise.
Thanks for the info...I actually ordered the part..then I thought...will 280Watts handel it? any thoughts on a a compatible power suply upgrade if it's not enough power.
