With 3 GB of memory, will 64-bit Debian run slowly?
I've ran Linux Mint 64 bit, even when running a AV scan, often will use less than 1GB of RAM (600-800MB typical). One thing to remember, if you run Google Chrome (or Chromium), be sure to go into the settings, go to the bottom & click Show Advanced Settings & at the very bottom, uncheck the option to 'Continue running background apps when Google Chrome is closed'. That alone will save a lot of RAM from being used. There are likely other Chromium based browsers where this feature (may be named different) should be deselected.
BTW, all four of my first computers were also Dell Latitudes (C640 & D610), so am familiar with the series. Some of the later ones, around the D620/630 series, had nVidia GPU issues that were solved in class action lawsuit(s), though there were many resold by then, second hand owners were left out of the settlement(s), yet many still cashed in as the first registered owner. By accepting cash in lieu of repair, all one had to do was prove it was purchased new by them, if registered, notices were mailed & all the owners had to do was opt in to benefit.
When new, all of these Latitudes were expensive, back in the early to mid 2000's, $1,600 & up was steep for a notebook, and these still are priced higher than most consumer based models of today. This is because of their rugged construction, built from the ground up for businesses on the go. The last of mine came from a hospital in Texas (Kaiser), and Dell sent me reinstall CD's for XP Pro, plus the drivers/utilities CD, as well as the installed media software, one for watching video, another for burning media. Something that they didn't have to do, fortunately I got hold of a compassionate customer service team member, while the call center was still based in the US. At any rate, Dell went above the call of duty in shipping me the package & I received it less than 48 hours after putting in the request.
Those computers just keeps on kicking, so I feel that you'll actually be extending the life of the computer by installing Debian or any version of Linux, as it's easier on the hardware. Unlike Windows, there's not dozens of processes fighting one another for every morsel of resources possible at startup. Boots faster, and as soon as you're logged in, can open the browser w/out any freezing.
While I've ran Debian, it was only in a VM, so didn't have to partition for a dual boot. That's going to be the first tricky part you'll have to learn to get started. However once installed, Debian is a rolling release OS, meaning no reinstall necessary, unless the OS becomes broken. Which often happens to newbies, and we all were there at one time.
You'll learn a lot through the University of Hard Knocks, as the rest of us Linux users has.
May have to give Linux Mint Debian a shot in a VM & see how I like it compared to a couple of years back.
