You may want to replace the motherboard, an AGP slot is almost a must have. There are not a whole lot of good PCI video cards out there. If you realy want to keep the current board for now you could get a Voodoo 3 2000 or maybe a TNT2. I suggested those 2 cards because they are inexpensive. I wouldn't put a lot of money into a PCI video card, the ones I mentioned are decent cards though.
