Just bought 3 new asus monitors and my little sister just asked me if they are windows monitors.... she is 13

I second this; should look for a PSU with 80 plus gold efficiency, don't skimp on PSU for such an expensive build

I made a PC part picker for you https://pcpartpicker.com/list/hsxFkT some stuff has different model numbers but its essentially the same

Coming with a 650W PSU doesn't mean it needs that much power.  No system needs that much unless you're doing SLI or Crossfire.

It doesn't really matter.  I downgraded you to a 1700 because there is so little performance difference.
 
As someone else said, building a PC is really easy.  The only tough part is picking out the parts, and we helped with that.  Cable management isn't difficult, but if you want to hide all the cables so it looks nice, it's time consuming.  Overall, it's pretty fun though.

Get the cheapest one, then buy this, remove the old RAM, and install it yourself.  It's important that you remove the old RAM.

Oh boy this one is a doozy... So my friend and I are talking at lunch and he goes "yo you play watch dogs?" So im like yeah i just finished downloading the thing it took like 8 hours then he goes wow your harddrive must be small i have a 2tb EXTERNAL hard drive in my ps4 so i downloaded it in like 2 hours. The resulting facepalm caused this:

I have to many non tech friends O_o Today my friend was saying how he is getting a new video card and i said what video card and he says exactly "I don't know all i know is that it's called and sd card and i'm getting it to increase my graphics frames and random Alternative memory by 2 more gigabits from 4 to 6." I can't even explain the incompetence of the people i talk to... oh and he then explained to me that there is only one kind of ram and its the sticks inside the circuit board  :huh:

Me like:
 

My friend had a really old computer and he wanted to play minecraft but then he realized that he didn't have the minimum required specs to run it (This computer is from like 1997) so he looked up, and i quote "How can i make computer have better specs" and then someone said get a graphics card then he called me and asked where he can download a graphics card. Then i explained to him that its hardware and he started yelling at me and telling me there has to be somewhere to download a graphics card. My friend is stupid...

Every single person that sees my setup: "O_O OMG why do you have 3 computers!"
 
 
 

Because "their was no point in keeping it if it didn't fit and ebay doesn't accept returns" I think we need a memorial service for that 780 and i only have a 770 so he could of given it to me

I don't remember if i said this before or not but every single teacher at my school has the projector projecting there screen at least 8 inches from the center of the smart board, and then they always complain about how the smart boards are stupid because they don't "write where they point"....
