As the title states, I'm looking to build a gaming PC for about $800. This will be my first PC build, so I do not want to go over $900 and waste money in case I mess up something xD. I would really appreciate it if someone could point me in the right direction, or maybe share your own gaming PC build if you have one =D. My hope for this build would, at the very least, be able to play all of Aeria's games at the highest setting smoothly.

Here are some of the components that I have in mind:
1) CPU
2) GPU
3) RAM
4) Motherboard
5) Hard drive
6) Optical drive
7) Power supply
8 ) Case
9) Operating System

Any helpful comments and/or recommendations would be greatly appreciated =).
