When did you bought this mobo? 2006? 2005? If yes then i think your mobo has 1.0 pcie slot version, so you can use any 2.0 pcie card. Is 5830 2.0 or 2.1?
Your board has 2 PCI-E x16 slots,and PCI-E 2.0 is backward compatible is PCI-E 1.0 so the card should work just fine on your board.Just make sure you have an adequate PSU.
