Upgrade of msi 890GXM-G65

[Sunseeker]

Hello,I would like to upgrade my system and fit a graphics card.I am a beginner and have only this year built my current Desktop. Any help would be appreciated as I find graphics a bit of a black art. I would like to be able to play the new offering from Egosoft out later this year.
