I need to build a home work station before I burn my poor laptop down. I use CAD software and 3D scanning software. Would I be better off getting a P4000 quadro with a 80k tesla card (or other recommendation) about $2400 or a P6000 quadro card for about $4800? Need performance. I have a lot of lag on my k1100m. I'm not a hundred precent sure if either of my softwares I use the most are accelerated for GPU action. I also don't know if the tesla card has to communicate through the video card or not possibly causing a bottleneck or not. If there is a different recommendation I'm listening. I do zero gaming. It is a pure workhorse only.
