>>only problem I have with em is that they fall out of my PCI slots too much and nearly shorted my board. <<
I keep envisioning an overworked ho. I put the retention screw in my SB!LIVE and haven't had any problems with it falling out!
I have issues with it, especially EAX. When I turn on EAX support, the volume on sound events originating from the front or rear is extremely low. So you can't hear a friggen rocket coming straight at you. I have the habit of turning to the side just to hear what the hell is going on (like in Half-Life).
