My computer's pretty old (eight or so years) and something of a Frankenstein's monster of various parts ripped out and stuffed back in due to parts dying etc., but even it can run most modern games pretty well. I'm not going to play Skryim on the highest settings or anything and I'd like it to run certain games like Victoria 2 faster, so I am looking around at getting a whole new rig soon, but this idea that you have to spend insane money upgrading every year or you can't play anything is complete poppycock.
