Some games are more taxing then others on the CPU and GPU.
Most games will run with no problem, except for the most demanding games will have some slowdowns.
When admin89 says that you can handle 2.5x Internal resolution on some games, he means that you can run the game at 2.5x the original resolution of the GameCube games, which is greater then 1080p. However, some games are more graphically intensive, so you will have to go down in resolution to about 720p. But it will still look better than original.
