I've been using my dad's desktop computer for a while, but i want my own desktop computer for my own use. I want to use it for visiting websites, youtube, email, typing papers, that kind of stuff. i am thinking about buying one refurbished from ebay, or even, "renewed" on amazon.com. What do you guys think about all this? How much should i spend? I will do my own research as well, but a website said if i want the desktop the last long, i should spend more money on computer that has a better processor, like i3 or even i5 processor. Is it even recommended to buy refurbished or renewed?
