well farming simulator is what i really want the destop for, also to run autocad abit, i dont do much 3d on autocad...its mostly 2d so im not really sure if i need that much to run it, surely it would take less to draw in 2d than for 3d rendering etc? i was gonna buy a prebuilt pc but thot i might aswell build my own for the same price that would be more powerful, also learn abit more and something that you can upgrade in future! at the minute im really trying to find out what is best for the money i would be paying!
