[zackfair197]

Sorry for bother you guy, i have a question! I'm using lenovo g580 model, i5 3210qm, intel hd 4000, i can't check motherboard infor bc it show "invalid" in cpu-z! Now I plan to upgrade cpu to use egpu for gaming! I want the best cpu for this laptop as possible so i choose i7 3840qm! Can i be able to upgrade it? The tdp on i5 is 35w and i7 is 45! I know about heat problems but i still want to know if i can do it! And talk about temperature, how bad it can be? Please answer and appreciate

Laptop motherboards usually do not support any upgrade options. All chips are soldered to the mobo. So upgrading a mobo is out of question in 99% of the cases.
