Gearheads of War

I also forgot to mention my budget, which is roughly 900 dollars, however I already have an nVIDIA geFORCE 6200 256 mb graphics card, so although it's not the best, that is the graphics card I will be using. I know that the card runs using an agp slot, I think pony express might handle it. So the motherboard I'm looking for has to have an agp slot and three standard pci slots(minimum).
