PC Made to Last w/ Good Performance Around $1K

###Build Help/Ready:

I plan to use this PC to play games w/ other tabs open, and I also intend to use this PC to run highly sophisticated graphing / investing tools.

This PC needs to be a sturdy, high-performance machine that can run AAA games at higher-max settings.

One could spend a bunch of money on expensive parts, or could simply find the best pieces that work together well to produce a highly efficient computer.

This needs to be around 500-1200 dollars.

http://pcpartpicker.com/p/CxHf6h This is what I have so far... maybe someone can help find parts that work together better at a cheaper price.

Help is much appreciated!

Thanks!
