We have older i3 gen 2 (i3-2xxxx) laptops with 4GB RAM and some have HDDs but for speed when we get to them we pop the HDD out for a SSD.
These are used for insurance work which is mostly web and office documents. They do well on YouTube and such as well.
https://www.crucial.com/usa/en/compatible-upgrade-for/Dell/xps-15-(9560) shows memory and drive upgrades if need be. I'd hold off till you figure out what you have there.
I saw a DELL XPS 9560 3GHZ i3-7100H 15.6" at a pawn shop for $300 and was wondering if anyone thinks its worth pickin up? The system is nice, just kinda worried about how the i3 would perform. Also is the hard drive and ram upgradable?
