Of course, I do. What you say now in contradiction to your first and second post:It's very slow, regardless of number of apps open. It just gets more so, the more is going on...
Why are you so intent on arguing about my laptop?
Besides of clearly focus on performance with multiple documents opened simultaneously, you are not aware (or don't care) about amount of RAM and other system resources available. You don't say whether you run plain preloaded OS with tons of bloatware, or a clean installation. It is why I mentioned clean installation.Essentially, I am looking for something that doesn't need to be rocket fuelled or full of bells and whistles, but that can manage lots of Firefox tabs/multiple documents/many emails, etc without gasping for breath.

I just need something that is not going to choke on 4.5 parallel Word documents.
You also don't mention about version of Windows you are running. From my experience 3 of 10 of computers running Windows 8.X (another name for Windows 10) suffer performance problems and poor responce figures due to the various device driver problems.
There are many aspects to consider before pointing for a poor CPU. Once you blame CPU on the public forum without giving any evidence, expect adequate response.
