Well, I cant say about your machine, however, my machine is purchased in 2008 and is still like new. The performance is same as the day 1 when I bought it in 2008. The only reason I am going for a macbook now is because now I have started feeling weight of this laptop after handling macbook air or for that matter dell xps 13 or x1 carbon or T460s. I dont wish to but I will have to let go off this master piece. let me know if you need this laptop for your research purpose. there's lot that can be done on this laptop hardware, but I don't have that much time to put on it. 9 years and still counting on. It still gives tough competition in looks as I have maintained it very delicately.
