If I were to talk to my grandpa about investing some money in an eight core mac pro, exactly how long would it last? At least 4-6 years if I take care of it? Or longer? If he spends 3000$ on a really good computer, instead of me having to upgrade my pc every year. It was 500 for the pc, And I'm going to have to upgrade again this year to have it at least dual core. I was considering a mac pro because of the cooling, expandability, and the operating system.
