So, I've been doing some 3D modeling on my MB, and I'm working with a fairly nice sized file (40 Mb), and my MB gets really hot, slows down, I get the beach ball fairly often when modeling, and everything leaves an image of itself where it shouldn't (the line moves with the mouse, but it leaves a trail). I'm using Google SketchUp, so you know. Is my MB's poor little GMA 950 being overtaxed? I'm getting a MBP in about a month with a nice beefy GPU and VRAM, but I'm right to say the MB is being overworked? Edit: The Mac in ? is a: Stock 2.0 Ghz C2D BlackBook, 1Gb RAM, 120 GB HD.
