Just as the title states, all the games I have been playing are stuttering, some more then others. UT3 will freeze for a good 10 seconds every 10 minutes, then increasingly longer. WoW will stutter, then stutter more often the more I play it. My guess is this is cooling related, as I have NO after market cooling. My question is, do you think it is more GPU over heating or CPU? My specs are in my sig.
