I have an iMac from 2009 with this CPU, and it still performs admirably for its age. Is it worth it today though? Not quite, like most of the early Core i3, i5, i7, and all the Core2 CPU's their viability fades by the day and its only a matter of time before they become unusable, but for now this chip is still alright and if you have an old machine laying around with this chip and wanna save some money you might as well restore it! [Mar '24 Randomgaming128]
