Don't get me wrong my laptop is a beast. It has been used everyday for eight years doing fairly intensive work. No complaints on this laptop.
That being said it is older and the less strain I have to put on it the better. When I do get a new computer I will probably clean this up, do a fresh install and use it as a mining rig, but until then I need to use my comp for work and do not want to dedicate the processing power to mining.
