Dell XPS 15 VS Dell

Hello everyone.

I'm trying to decide what laptop to choose as a portable working station for video editing. I am a beginner (not sure if that is an important thing to mention). Right now, I am torn apart between:

1) Dell XPS 15 9550

Configurations:

– Processor: Intel Core i7-6700HQ
– 512GB PCIe M.2 NVMe SSD
– 16 GB DDR4 Non-ECC SDRAM 2133MHz
– 15.6 inch 4K UHD (3840 x 2160) InfinityEdge Touch Display
– NVIDIA GeForce GTX 960M 2GB

AND

2) Dell Precision 5510

– Processor: Intel Core i7-6820HQ(3,60 GHz)
– 16 GB DDR3-1600MHz
– 256GB SSD
– nVidia Quadro M1000M 2Gb

I would be grateful for any advice from you.

Thank you.
