Hi all, I had AMD athlon 3200+ processor(2.0GHZ), 1gb RAM, 160gb hard-disk system. I found out that games such as prince of persia, hitman, etc are unable to get installed on my PC. Even small game like 'Little Fighter' shows poor graphics. I am not that good at computers. I want to upgrade my system to the latest available. Can I go with Intel or AMD has the best?. What to look first while estimating a processor's performance... is it its GHZ, hyper threading or dual-core..please help me out to reach a solution.
