Hi, i have a Lenovo thinkpad carbon x1 tablet 2nd gen. It a 2 in 1 device and it's a i5 machine with 8Ram. I saw motherboards with I7 and 16GB ram for sale, so i want to know if it's possible to change an i5 motherboard with an i7 one with more ram. If its possible, please let me know. I need these specs for my creative work and i don't have the budget to buy a completely new machine.
