If you need a wireless network connection I recommend getting a USB wireless card, not an internal. There doesnt seem to be any performance difference and the USB is portable to another computer and easier to work with if there is a problem.

There's no point buying a tri-channel memory kit for your system, get a 4GB dual channel kit instead. Only x58 mobos utilise triple channel memory, as that is not what your system is based on, it won't go.
This is good for quite a lot cheaper http://www.scorptec.com.au/computer/35101-ocz3p1333lv4gk. Apart from that good.

Good call Silvune, I totally overlooked that. AMD motherboards only want 2 sticks of RAM.

I'm sure I've overlooked that kind of mistake when offering advice b4. I don't remember having a good excuse tho, hopefully you do
