I only need hardware for office tasks and hardware for max browsing speed. i allready have the i7 6400u on a thinkpad. I am thinkong to buy a desktop. You believe worth it ?
A desktop is more upgradeable, you can have more storage drives, more ports, etc. I have no idea if any of these apply to you. All I can say is that on the basis of CPU alone, it's not a worthwhile upgrade.
