Hi guys. I am thinking of updating my system to cater for 3D programs and rendering. Any advice for CPUs, memory and graphics cards? Is a P4 3.2 OK? Is a dual CPU really better than one? Any advice would be greatly appreciated. I am prepared to spend a little money as long it makes a difference. ie I don't want to buy a twin CPU if the rendering speed is not that much faster. Kind regards, Mil.
