well then in RAM and Graphic Card you'll do fine in both games.
The CPU however in Silent Hunter 5 you're just above the minimum requirement.
And in ArmA 2 Operation Arrowhead you're below the minimum requirement in CPU power.
However I've seen videos online people playing ArmA II (not Operation Arrowhead!) on a Intel Duo Core E4500 @ 2.20Ghz just like yours.
