Currently the graphics card is the GeForce 7300 that I found not to be compatible with 10.8. I did some research and I discovered that it is possible to change the graphics card and using a hack to install the 10.8 on the Mac old.

@lord danone : GTA III tournait à fond avec une geforce 4, Vice city a fond avec une geforce 5 et San andreas a fond avec une geforce 6 (c'est mon époque geek je me rappelle bien ;). alors avec une X1600 ou une X3100, 0 problèmes a mon avis. reste a voir l'optimisation ... 2ff7e9595c
