Hi Guys!

(This is my first thread, maybe in the wrong section)

I bought this laptop 2 months ago. Lenovo Z5070.It came with a GT820m and i5 4210u/8 GB DDR3.

I had no choice about the specs at that time. Now i want to upgrade these however i am not in a position to buy a new laptop. I have heard about an external graphic card too. I want pure performance to play game like watch dogs @ 60fps without bottleneck.

I can/have upgrade my RAM to 16GB and i have a budget of 400-500 $ for all this.

Please someone help me out!

Thank you!

The device is for desktops. Laptop GPU usually are integrated on the motherboard.

Laptop cooling might not take additional heat from faster CPU/GPU.

Space is limited in laptop and AFAIK there is no water cooling kit for laptop.

Laptops are not the best for gaming. Laptop CPU and GPU run at lower voltage to reduce the excess heat and lower voltage means lower performance compared to desktop CPU/GPU.

I have a i7 and AMD 6990m laptop that gets hot and noisy fan (running at high rpm because of heat) when I play games like Skyrim or Diablo 3.
