Your machine is very good in my opinion. Only you can decide when it's time to upgrade!

Can you play all the games you want to on your current rig? If yes then dont upgrade...if No then there probably still isnt any point in upgrading because all your tech is the still new.

no need to upgrade unless you play at 1680x1050 / 1920x1200 and that upgrade is only justifiable when there will be DX11 game by next year include Battlefield Bad company II : Bad company II will Look much better on pc :D
