The x1950 pro is a PCI-E card not an agp.
there are agp and PCI-E version of this card coming out. i believe gigabyte is producing the x1950pro in agp form for about 250 bucks.. :P just thought you might wanna know :P
It would be wasted on a 3000+ anyway - you'd really want something like a 3500+ or better to make the most of the card. Of course, you can always overclock the 3000+ to 350+ speeds or better.
