Suggestions for new computer($1200 budget)

Hey I'm looking into getting a new computer at around Christmas. I have a $1200 budget and I will be gaming/botting on it. I need a tower and I need a Os.
So far this is what I picked out for building my own http://pcpartpicker.com/p/ngzG
Thank you in advance

 

For a pre-built, this is a fairly good system..
Anyways, I always suggest customs..
I will edit this post/make another post with a recommendation of some parts..

Thank you for your input, I'm going to compile a list of the parts on pcpartpicker.com. I may have to downgrade quite a few things because I still need a os and ram

 

I'm sorry, I calculated RAM with the price but didn't post it, will edit it in a sec.
If you really wanna buy an OS (Most ppl don't buy it, alot of other ways to get, note that I'm not advising to use it) get the windows 7/8 or maybe Linux (which is free)
You can get a lower quality SSD, HDD, Case etc..

 

What do you think of the build I posted in the op?

 

Really good, http://pcpartpicker.com/p/nk3q is what I suggest..
It's 1320$ with OS, (You don't really need OS, other ways to get for free)
1220 without.. will serve you a plenty of years!
It's with a CPU cooler, more Wattage, better video card (It's actually the same GTX 670 but another brand, 3 fans (highly overclockable))
