I want to build a desktop. What do, Kiwike?

[Sir Prize]

Don't get a NVidia Graphics card. Why?
Because they are overpriced. They use cheap marketing to get customers. Like implementing things into games at the very last moment before release so that no one with a Radeon card can run it. (They own PhysX, so don't give me anything about not making games.)
Don't get more than 4GB of RAM. Why?
Because you don't need more than 4 when gaming. It's prepostrous.

Get a 16+GB SSD, not above 100GB. Why?
Because you're only going to keep the OS and the most used programs on it. And it's expensive as fuck.

And that's probably as much advice as I could give you.
