Not more difficult to upgrade at all. In high power gamong applications, more expensive intels will beat more expensive amds, but in a $500 rig, and in this case, i believe the amd is better. Games are more based off of gpus anyways. Plus the cpu i told you to use is a quad core, so applications that use multiple cores will fare better with it. You should be able to play most games on high setting, definately medium. I believe laptop just does not like amd, which is why he chose the intel.
