So my current computer is a piece of stuff and I would like a better one. Is there a website or place where you can build your own computer at a reasonable price (tell me what I would need, please), or if someone could recommend me a prebuilt computer that is decent at a good price?
Newegg is your best bet.
If you want a computer better than yours then you need,
Case
Motherboard
CPU/Processor
CPU/Processor Cooler
RAM/Memory
GPU/Graphics Card
Power Supply
Optical Drive
Harddrive
That's it.
If you tell me your budget I could give you a direct list so you don't need to go searching.
EDIT: I need help with networking.
I have my modem and router in my attic were my dad has his office and computer. I got a new desk and plan on building myself a workspace but our attic does not have enough room left. The only other place that is ideal is my basement. My only problem is that I plan on getting a new computer for my workspace but I do not intend on buying a wireless card or anything because I just want a strait cable connection to my internet. Only problem is that I am separated between three floors of housing :/ What do?
