Hi, by chance this is the machine I run... earlier version 5510 with 8-core i7. I have actually two... have a lab with a lot of Dells.I am writing this right now on a nice Dell Precision 5550 laptop with 32 GiB of RAM, a wonderful 4K screen, and an 8-core Intel Core i9 processor. PixInsight runs like a dream on this machine with Kubuntu Linux 20.04 LTS.
