Thanks, Guys.
I would be unhappy if I spent a lot of money on a machine and then it didn't do what I needed. I don't care how fast programs open, etc., but it needs to like not hang up when viewing video, etc.
The predecessor's predecessor, Gandalf the Grey, was a great machine. For years. Windows XP (I still have it, and it still runs. Also a Dell.) But it couldn't handle the internet or streaming video...
Have dropped a line to the "we build it for you" place down in England that someone recommended and am waiting to hear back what they can do for me. I mean, if I can salvage the DVD burner from the old one, great. But apparently they are now cheap, as external drives.
I loathe computer shopping, have I mentioned?
I have it down to two Dell machines, which seem otherwise identical. The only difference appears to be the processor, at a cost of another 100-ish pounds for the i5.
Intel Core i3-7100 processor (3MB Cache, up to 3.90 GHz)
Intel Core i5-7400 Processor (6MB Cache, up to 3.00 GHz)

I've also seen HP desktops for cheaper, but had a nightmare with HP service a few years back when the Daughter had a defective laptop from them. It was literally a small novella there and left me with the "never buy from HP". I'm also looking at Acer and Asus. But so far the Dell seems with the i3 seems to be the winner. Had two Dells now, excellent machines.
Alternately, there is spending half as much on a reconditioned machine. Sigh. The Dells only come with one year warranty, which is pretty much what the reconditioned ones do. Aieeeeeeeee!

AND.... John Lewis has it on at the same price as Dell, except is offering a 2 year warranty. Dell, on the other hand, is offering 10% off with a one-year warranty.
I hate my brain. I just need for there to be one flavor, not eighteen, to choose from.
