I’m an XPS 15 user. My xps got fried after using it for 1.5 years. Let me warn you. Don’t buy a xps if it has a nvidia graphics card in it.. The nvidia cards in all xps laptops are faulty in design. And they will last only for maximum of 2 years (just as mine did). When I googled, I saw many frustrated users like me. Here’s the proof -- https://en.community.dell.com/support-forums/laptop/f/3518/t/19339656.aspx.
Just think about it. After the problem starts, you will have to call the dell customer care, and they will tell you to replace the motherboard (because u can’t just replace the graphics card, since it is integrated to the motherboard) for another 8000 rs !! The main part is - this new replacement motherboard will also be having the faulty nvidia graphics card in it, and you can use the laptop again for another 2 years max.
Think a 100 times before deciding on xps laptops with nvidia graphics cards.
