I agree, though I consider the dedicated GPU in the 15" Macbook Pro to be at the bottom end of "mid-range". :) Nvidia's GPU model numbers go from, at low end, X10, to, at the high end X90. X50 is right in the middle. Sorry, I just had to leave a comment here, because I found my Nvidia integrated GPU in my 2009 13" Macbook Pro woefully inadequate for CUDA computation.
