Graphics Settings

Hey folks, Just updated to 2013 from 2006 and wow what a change. I am having some small issues with graphics and think it may be my settings need tweaking. I am running a Dell Optiplex 990, Intel i-5 3.10GHz with Windows 7 X64, 8 GB Ram and an AMD FirePro V5900 graphics card. What would be the best settings for this graphics card? I have seen threads about "anti-aliasing" and other stuff but what does it all mean? Any suggestions?
