Hey guys I appreciate the discussion about Dell and Windows, but after all, this thread is all about ME. ME ME ME!

Seriously, good discussion and insights. And Trev you may be right about the machine not having been completely repaired the first time, but of course I have no way of knowing for sure. Since I still have 14 months on the all-inclusive warranty they threw in with this box as an inducement to buy, I guess I'll just keep re-installing TS and see what happens.
Perhaps for some reason I do need to avoid using some of my "Enhanced" cloned versions of certain routes made with prior versions of TS with TS17. As in make new versions of them using TS17. But again, no one else has expressed a problem here.
I do have a feeling the R9 270 graphics card is not up to the job, even though its specs are good enough and Dell says it should be fine for handling the addiction we all share here. The fans have always revved up considerably and made a whiny racket when I launch the sim. That includes the first R9 270 card that self-destructed and the new replacement R9 270, which whines even more at times. It just sounds like it's "straining." And running the sim in Hoboken and nearby areas of the NJCL route really seemed to be pushing the graphics, including some stuttering while the card whined away. Since I doubt this machine will handle a seriously more powerful card like an nVidia 1080, I'm stuck with this, and especially until the warranty ends and changes can be made without jeopardizing the warranty or I get a new machine.
I've always felt more comfortable with nVidia cards, but the more powerful ones were not available from Dell when they put this package together. Now it looks like NVidia is all they are offering with the XPS towers, as well as the Alienware line. I guess they got a better deal, or maybe too many problems with Radeon cards. I'll never know.
As for Dell reliability - sitting next to my XPS Special Edition is a Dell Dimension 8200, purchased in 2002 to run ol' MSTS and do general duty. The doggone thing still runs fine. My computer guru friend here is itching to get his hands on it to clean it up and clean it out. As for the latest Dell boxes, all he'll say is, "They don't build 'em like they used to." I am a believer.
