Specifically, I just purchased a fully refurbished iMac G5 and I am interested in playing several old games on it (most likely Marble Blast Gold and Knights of the Old Republic). Although I know the games will run well on the computer, I am wondering if (generally) running graphics intensive programs will decrease the life expectancy of an iMac (specifically with regards to an iMac G5 Mid 2005 Model) in both the short and long run.
Will frequently running graphic/hardware intensive programs harm (in the long run) an older iMac?
Note- I am not looking for an opinion or subjective account, just some level of reasoning behind why it would or would not impact the computer (i.e. thermal paste wears down, processor runs to hot overtime, etc...)
I am still new at this so if my question is to vague or opinion based let me know and I can change it.
