Best Dell pc/Customized pc for Autocad 2008 and 3D modeling.?

they guys who have already answered your question are good, but I personally would advice some DDR3 memory, which will decrease loading time and make your multitasking easier. a con here is that you need a DDR3 mobo. so you have to pay attention to that when your picking a mobo. and another suggestion is to check if your local computer seller makes custom computers. then you can go cheapest. but otherwise the XPS 650 is the cheapest computer that can give you your needs.
