Is there a newer, better laptop for me than my Dell XPS 15

I have a Dell XPS 15 9530. I’m wondering if there is anything new that is better. Of course “better” depends on what you want. I do a lot CAD and graphics and starting some video. I also travel with my computer so portability is important. The specs that matter to me (and what I have on the XPS 15) are:

1. Weight: 4.5 lbs. (Maximum weight 4.5 lbs. Lighter would be better.)
2. Screen size: 15.6” (I don’t want anything smaller, and probably not larger to keep the size of the laptop down. I need it to fit in a briefcase and be truly portable.)
3. Screen Resolution: 3200x1800 (I have found this to be unusable on my laptop because so far software titles are too small and can’t be adjusted. I have set my laptop to run at 1920x1080. However, I use an external monitor at 3200x1800.)
4. RAM: 16 GB (I want more)
5. CPU: Intel® Core™ i7-4702HQ CPU @ 2.20GHz 4 Cores (I want faster)
6. Graphics: NVIDIA GeForce GT750M 2 GB RAM (I want faster. I do a lot of CAD and graphics work)
7. Hard Drive: 512 GB SSD (I want something bigger. Maybe a 1 TB hard drive, not SSD, would be OK. I routinely use a USB external hard drive because I can’t fit everything on the 512 GB SSD. I probably will want bigger than 1 TB in the future.)

Any help will be greatly appreciated.
