I am looking at upgrading from a Dell Precision M6800 laptop to Precision 7740, and wondering best RAM.  

 

FWIW, on current Dell M6800, i7-4940MX, 24GB 800MHz RAM, Nvidia K3100M, SSD = Crucial 1TB SATA M550; time to open:

(1)  Assembly with surface laser scans = 2:59 to open  (yep, you read it right, three minutes).  Memory used 2.1GB, momentary CPU usage 80-90%, mostly CPU = 13%

(2)  Different assembly drawing = 1:04 to open, memory =  1.8GB, momentary CPU = 26%, mostly CPU = 13%

 

New candidate computer = Precision 7740, i9-9980HK, Nvidia RTX4000, SSD = Samsung 2TB 970 EVO Plus. Two possible choices for RAM:

 

(a)  64GB (4x16) SODIMM-3200, Crucial $280

(b)  128GB (4x32) SODIMM-2666, Samsung $552

 

The above suggests raw speed matters most?
