I have a HP Pavilion dv5z 1000 notebook with AMD Turion x2 dual core processor and ati radeon hd 3200 graphics. From what i hear, the cpu is good enough but the gpu sucks. I then did some research on upgrading the gpu and found that it is not possible to upgrade the gpu in laptops. Can i just remove the motherboard and purchase a new motherboard and attach a new gpu (ati hd 3870) and use it in my laptop? How much is it going to cost? Please reply soon.
