Due to a standard of "backward compatibility" most, if not all, 8X cards are 8X/4X.
Whether or not these games will play on a 4X level I do not know. I would say the latest games probably would not.
The web site for the game should have the minimum requirements. If they specifically require an 8X card then your motherboard just can't do it.
Another consideration is the RAM of the card. Most new cards are 64MB or 128MB or 256MB. Again the game requirements for this should be listed with the game.
