Hey guys,

I just wanted to build my own gaming desktop and i was reading around and this is the system i concluded with. I'm not sure if they work well together - my general aim for this system is to play video games with above average settings. There are still parts im debating which one to get so if you could help that would be most apprecitated. My budget is around $1500 AUD (i live in Australia) - things tend to be more expensive here. I'm looking for parts which are most cost efficient - i am not spending say $100 more for no real difference.

Thanks in advance!
