Hello. I have a question regarding an ssd upgrade. My mom has an old acer e1 521 laptop which is really slow (amd dual core 1.4GHz, wd 320gb hdd, 3gb ram). I was thinking of replacing the hdd with a crucial mx300 ssd which I bought recently. So here's what's bothering me: will it make the laptop faster considering the slow processor or should I consider buying a better laptop with a more powerful processor! I'm really not a pc expert so I would be very grateful for any response. Cheers!
