I have felt no pain on my i5 Surface Pro 3. It outperforms the decent rig my office provides. I run multiple instances of VS, leave stuff open all the time, massive Chrome tab abuse... The fans only come on while streaming video AND compiling, etc. It doesn't hiccup or grunt.

I wasn't 100% sold on the price/value ratio when I bought it, but now am totally happy I did. Great machine.
