I have a toshiba tecra a2 laptop with a measly 256mb ram. Now my problem is when I play old games like Fallout or Planescape my cpu usage bumps up to 100% and it produces more heat. I don't lag or have any problems running at full quality but I can't play for long times since I know it'll probably overheat or something. Now my question is if I buy a GB of ram will that fix my problem and keep my cpu usage low? Or is that because of the processor? And if a gig of ram will help what do you guys suggest I buy? Thanks.
