Newbie to Building Help!

[itsanerdygeekthing]

I am wanting to build a gaming pc that will be able to run WoW and other games as well as be able to stream to twitch as well if I want to. I am a newbie when it comes to this and have no idea where to start. I want to spend around $700 but have the ability to make changes to it later and upgrade where needed.

Budget: 700
No need for peripherals
I want an OS
Res: 1920 x 1080
Country/state: US TN
Rather not use used parts

Thank you,
Stephanie aka Its a Nerdy Geek Thing

p.s I am a total newb and just saw there is a build section if this can be moved. My apologies.

Thank you for the information. I like a lot of what you provided and the OS links are super awesome too! I also forgot about needing wireless as well.

You can usually find a wireless N adapter on Amazon. I don't believe I can send a link, but the keyword to search for is "Wireless Adapter for PC".

I have used the Netgear N300 before, but really any of them should be just fine. Especially, considering most are default Dual-Band now.
