Auto Cad computer?

[slaya]

Hey, my friends brother is looking for a decent computer for college with his auto cad work..

He's asking me to build him something for cheap but he definetly want's Intel and Hyper-Threading support..

I'm wondering what would be a decent CPU, motherboard, and video card.. I can figure out the rest..

I haven't set a price range on this just because I know nothing about Intel CPU/motherboards or non-gaming video cards but cheaper the better.

Thanks
