Hi I was considering the New Dell 15 7000 series with Intel core i7 5th gen, 8gb of ram, vs the HP probook 650 g1 with intel core i5 4th gen, 500HHD 7500rpm, 8gb of ram etc. Which one of them should I consider for 3d programs as Autocad, Sketchup, Lumion etc. I will gladly consider another option. Thanks!!
