Is it better to use a cpu with integrated graphics such as core i7 2600/4770 as a primary display and use the graphics card entirely dedicated to 3D rendering, so that the performance of graphics card won't be compromised even a little bit by the distribution of graphics memory.....???
PS: Basically i'm trying to build a budget 3D animation and rendering rig. I use Blender. (Already bought ASUS geforce gtx 980)
