I am trying to make some games on steam not lag the most difficult one I have to get to stop lagging is Rage and I'm looking for a processor and video card combination that wont kill my lap top. its running windows 7 ultimate with an AMD Sempron m120 2.10 GHz 4 GB ram and a 64 bit operating system. any info would help I'm sick of it taking 2 hours to drive a 4 wheeler to the first mission and then it crashing.
