hi guys, i want to build a 3d rendering / modeling pc, but i don't know to pick the right parts for my pc. could you help me to choose the right parts? i want to use some program like: poser, blender, and unity. i also want to use this pc for playing games like skyrim. and my budget is around $800 (or $900 if necessary).(my priority are intel cpu and nvida gpu, but the others are fine)
