The only "games" a PCI-only system is able to play are 2D. Chess, Mah-jongg, Poker, Solitaire, Vegas Slots, etc. The PCI bus is too slow for real gaming (at least, more recent than about 2002). As bad as plain PCI is, it makes no sense to look for any video card costing more than $20- $30, like an FX 5200, or a Radeon 9200.
