I bought a Lenovo Z570 with:
-Intel i3 Sandy Bridge processor,
-4g of DDR3 ram
-Lenovo Emerald Lake Motherboard
-Intel Integrated Grapics (1814mBytes)
I want to upgrade the GPU specifically, but if that is only possible by upgrading the CPU than thats fine by me. Most importantly, can i add a higher- end graphics card either externally or internally? (Preferably nVidia)
Well I do not think that dedicated gpus can be added to a laptop leaving some rare cases. Changing the CPU will make you go up to hd4000 from your current hd4000 but let me tell me before hand that if you are a gamer or a multimedia professional that change will be negligible.You can contact lenevo for adding the gpu to be sure but I Think the answer would be no.
