Hi!
I need a new computer to meet the needs of intensive 3d graphics (maya, 3ds max, etc), rendering, and gaming. I am pretty novice when it comes to hardware so I really need help! Willing to build it or buy it pre-built..nothing over $3500…cheaper = better 
so yeah, top notch graphics card (ati or nvidia?), pcu (intel or amd? which model?), amount of memory? open to mac or pc…which is better for intense usage?
Thank you 
Thanks so far everyone!
I am american, not australian.
What sites can I create a custom computer on? That would be much easier than piecing it together myself.
