My cousin has a 1300 dollar budget and would like a custom pc so he can run auto CAD. The software is covered already and he would like a lot of power to design heavy engineering tasks. As this will be going to college with him wherever he chooses in 2013. He is the same as me at 17 years old so he's paying for it himself. Any good advice on part lists because he has the GTX 690 already chosen which he could pay for via his parents but still, if you could build a list with auto CAD tasks in mind that'd be great.
