First Time Build - Gaming Rig (Australia)

Hi Guys,

I am planning on building my first pure Gaming PC, which is also my first build and I have done some research and have to put together a list of parts that I wanted to include in my build. Money is not really an issue with me, but if I'm buying something that is not needed or has a cheaper alternative than by all means let me know.

I appreciate as much feedback as possible.

I am also from Australia, which rules out a couple sites regularly used here to source pc parts.

Thanks!

Approximate Purchase Date: August

Budget Range: 2000-2500

System Usage from Most to Least Important: I will be using it mainly for gaming (High end MMO's, Skyrim, BF3 ect.), purely gaming tbh as I have a laptop to watch movies and surf the internet with.
