There typically are four issues in GPU compatibility: Power draw and connection; mobo has the required slot; BIOS will allow the upgrade; Card will fit in the case being used.
Mobo has a PCIe X 16 slot and your BIOS appears to support upgrades. I have no idea about the case except that it does come with an HD 5850 which is a pretty large card. Looks like you are good to go.
