I've been considering getting a gaming desktop for a while, but it is hard to find good builds on the net. My budget is around AU$1000 (650GBP), and I'm looking for something that will run today's games on a high setting, as well as being able to last for a while before I need to update the hardware. I am also willing to self build it, if that is a more cost-effective way to do it. Any thoughts?
