Bought this for a work laptop. Already had 16gb of RAM, so that's not bad, replaced the HD with SSD, improved the performance.There are two things that knock it to 4 stars for me, the laptop fan runs more than any computer I've ever owned, and tried a few tricks to resolve that, nothing yet, and credential manager service needs to be restarted occasionally. Could be the OS build, but didn't have the problem on my previous laptop.
