I have two mid spec PCs, both laptops but still good spec, I simply just can't run the game on either, the lag is unplayable on my 4GB ram ATI PC and the frame rate is 5FPS on my 8GB machine. I can play GTA 4 on medium/high settings but cant play this RTS game. It's quite simply a joke and the gameplay changes in my opinion aren't that drastically different. I would say overall don't bother, from the sounds of the community modding is gonna remain on em4 for quite some time. We've had the same things with em2013 etc etc all pretty crap follow ons. That's just my opinion.
