Are all these computer parts compatible with eachother?

Hi, I'm building a gaming computer and I wanted to know if all of these parts are compatible with eachother
Here's the link: http://pcpartpicker.com/p/38lMJ

I also wanted to know if this is a good build and if it can handle demanding games like Sims 3, Minecraft, Bioshock, L.A. Noire, Tomb Raider and Borderlands

A third thing I wanted to know is if I need a sound card. I'm a noob when it comes to computer building so I'm not sure if the motherboard has sound integrated into it or not.

Last but not least, the internal harddrive that I chose, is anyone familiar with it? Is it quiet?

Thanks!
