Hello, I am thinking to buy a HP Elitebook 8470p and I would like to add later a 4 core i7.Which one should I choose so with the i7 will not have heating issues? HP Elitebook 8470p + dGPU OR HP Elitebook 8470p + iGPU Probably with the iGPU I will be okay but with no evidence from existing users I cannot be sure.I would prefer the one with graphics card but if it will heat up and will throttle i will get iGPU I saw also about Dell e6430 which has nvidia optimus for better battery life and it is suitable for i7 quad but is little bigger than t430 which I have and bulky from what I read Thanks a lot!!!!
