I have an early-2011 13" MacBook Pro (2.3ghz i5) and a Wacom Intuous Pen & Touch. I notice when I sketch really quickly in Photoshop CS6 the CPU starts to scorch, up to 95 degrees Celsius. Then, the fan kicks in. When this happens it disrupts my workflow as I become concerned I'm causing undue stress to my processor. Does anyone else with a similar machine or one of an older vintage experience this? Would the base quad-core 15" MacBook w/ Iris Pro handle this task without breaking a sweat? Thanks!
