So I've had this decent computer for awhile now, I think just about two or three years. It's worked great. When I got it (it was a Christmas gift) my mom took the liberty of upgrading the Graphics Card so I could play some high end games with it. However, as technology evolves, my computer doesn't, so I feel as though some of its parts are in great need of an upgrade. However, I know a Pre-Built computer is not friendly at all with replacing parts, and it could be more trouble than it's worth. I also know that it tends to be more expensive to buy parts compatible with a pre-built computer. So I'm wondering if it's even worth buying replacement parts, or if I should just go all in and build a computer from scratch?
