A simple read on the Intel help site shows that quad core processors are not recommended for certain games, and may never work with older games. There is a quad core fix there working on with some gaming companies but in the mean time, set the affinity of games to run on one core.


Basically you jumped the gun and got something thats too new and have to use just one core to get stuff to run correctly. This is the same issue that us with duel cores had until the fixes came out.
