Can i change the graphic card of my laptop (Inspiron 5567) from R7 4 GB to Nvidia 1080 4 GB?
please help me, because this R7 is not working as expected from reviews. Thanks.
No, you cannot. If you need better video, you need a new system - that GPU is available in the Alienware 17 system as an upgrade (the card alone is over $650 as an upgrade in a new system, so just the GPU is likely more expensive than the cost of your current system).
