its not the card fitting on the motherboard that you need to worry about. As long as the board has a PCIE x16 slot it will work with the motherboard no problem. Its the card fitting into the case that you should be more worried about. a 9800gt isnt that large of a card so it should be able to fit into most pc cases. Oh and BTW your links are not any good they dont lead to what you are talking about.
