I got a XPS15 with i7 quad core Skylake, 16GB DDR4 RAM and 1TB SSD. Immediately upgraded it to 32GB. Ran it for the first time with a sizeable data reduction task this week and it chomped through it. Didn't even have enough time to make a coffee, whereas my old laptop (single core i5, 4GB DDR3 RAM) would have probably crashed about five times an hour and sometimes took 16 hours to run the same datasets. I'm not super-techy like some of you guys but I know an improvement when I see one!
