Looking for a new RTS game to play, nothing too graphically heavy. I have a 3 year old XPS M1710. Ive played most of the total war series apart from Shogun 2, Civilization V is great - but im looking for an RTS build up your base and send in the troops sort of thing, similar to command and conquer but with modern units, no telsa coils,future units etc

Anything already out there or coming out soon? Thanks
