Hi All,

I would like to change my PC and by Dell 27" but I'm undecided between the different model and I'm not sure to understand the differences between those:

XPS 27" 7760 >>> Link seems to be very good but old i7 (7 generation instead of 8) processor compared to other

Inspiron 27" 7777 >>> Link very good in terms of processor (8 generation) and graphic Nvidia.

Precision Workstation AIO 5720 >>> Link if I'm not wrong seem to be similar to the XPS and similar features.

I should use it as 360°, some editing photos (Sony A7 Full Frame) with Adobe Lightrom and very simple editing on Adobe PremierePro for FullHD videos on 50FPS and normal usage on internet navigation and

Please could you support me with any feedback about the best product based on these information and to understand the differences between the above model?

Really thanks,
Edoardo
