New Computer Help. URGENT!

So, its christmas, and i finally need a new computer.
I was thinking that building mine would be the best bet these days since i dont need any of the other crap in a package or something.
My pricetag is about $700. Maybe a tiny bit more.
Fallowing is what i picked out, can you tell me if theses are good choices, and that they all work together. I tried my best and are pretty sure they do.
But i wanna double check.

Answer #1
Look fine to me, everything should piece together nicely. If your going to or want to put a little more in it look for a 256-512 bit video card, you won’t be disappointed.
Answer #2
