Hello... Like the title says, I am a newbie in this... I acquired a lenovo y510p in December, and It came with the nvidia gt750m and the useless wireless centrino card from intel. I bought from Amazon the Intel AC 1760 wireless dual band, just to check that I cannot install it. It's unauthorized, blablabla. My question is. I know i can downgrade bios to 2.xx and use the wireless card i bought, but what about the graphics?, There will be no problem if I plan to buy another gt750m for the ultrabay slot?. Thanks in advance.
