I need to buy a new computer, but i can't decide what i want, so i figured maybe you guy's could help .
I need it for autocad. I do alot of 3D and i don't want a computer that will make me wait 40 min to finish rendering.

-AMD Athlon MP 2x 2000+
A7M266-D ( dual CPU) AMD MP
2 x 512m MB RAM DDR PC2700

or

-Intel P4 2.2 G
