Building my first Gaming PC

Hey Guys!

I was getting tired of Console Gaming and decided to build it myself. Problem is that I am a noob when it comes to building it and knowing which parts I need.

Build I made in PcPartPicker.com

http://pcpartpicker.com/p/2hSJA

or with smaller PSU: http://pcpartpicker.com/p/2hSLf

First one without display: http://pcpartpicker.com/p/2hSG8

Second one without display: http://pcpartpicker.com/p/2hSNt

Some of my major concerns with this build is that the PSU isn't big enough because I have the intention of Buying the same GPU in the build down the road once I got enough money because I have a limit of $1000 ~ $1100. Do I need a sound card or is one already built into the GPU or Motherboard? Is it necessary to buy a CPU Cooler now even though I will likely not overclock at any time even after getting the second card and putting them in SLI? Do I need a Wired Network Card to access the internet through a wired connection? Should I get Windows 7 or 8? Are any of the parts bottle necking each other? Can the motherboard handle everything that I wish to put into it?

My goal with this build is to be able to run Skyrim at 1080p with an ENB with 60+fps, Bioshock Infinite at 1080p, Age of Conquest 2, word processing programs like word, and watching videos and editing them.

Sorry for writing so much and thanks for any help you may provide me with!

You don't need a sound card unless you're an audiophile, and you don't need a network card either.

This is what I recommend for your budget:

Well, first with the questions.

750W is plenty for an FX-8320 with two med-high range graphics cards.

Motherboard's onboard sound is just fine for gaming and pretty much good for almost everyone except audiophiles and sound editors.

Buying a CPU cooler now doesn't hurt.  It'll make your CPU run cooler and often quieter.

Motherboard has a ethernet port.  You shouldn't need another card for your purpose.

I like Windows 7.  It's up to your preference.

Parts aren't bottlenecking, really.

Yep,  Great motherboard you picked.

I changed your build a little bit:

Cheaper RAM(why not? it should perform just as good as the kingston one you picked), 120GB SSD + 1TB HDD, GTX 770 will be stronger than a 760, and Rosewill's Hive PSUs are great.  You can add another GPU later on, and with an aftermarket cooler, overclock the CPU a bit.  For the aftermarket cooler, the Hyper 212 Plus is a great option.

Thank you so much for your input!
