The laptop has been used for a year and the GPU module (RTX2080) decided to die after plugging in and playing games constantly. This however can be replaced easily with an OEM GPU module that you find on eBay itself. I don't game anymore so I don't think want to fix it as I'm using a Mac now.
For those of you who don't know about these laptops, the CPU, GPU module, RAM, etc. can all be replaced. Yes! even the GPU comes out as a separate module and the CPU is exactly what's in a desktop with the LM socket.

Everything else works perfectly. 
All original accessories
Box included,
Two chargers included.

Spec: - 
i9-9900k (overclockable processor)
RTX 2080 GPU (Should be replaced)
32 Gb RAM
256SSD
1TBHDD
144hz Display (games are like butter)

I bought the laptop from dell for 3460 pounds. However, since it has been used and the GPU will cost for replacement. Hence, the price listed above.
