Update as of March 3.  The card came in and Dell was very quick to send a tech to replace it, so I do believe everyone else when they said the on site support was very good.  We installed the new video card and I ran the dell site tests on it, which still came up as "failure" with no resolution.  Will keep using the card and advise if it goes down again.  The tech suggested that my issue (loss of video, keyboard and mouse at the same time) could also be a Motherboard or CPU issue.  I would have rather tested those parts than wait a month for a 3080, but I'm hoping the problem is now solved.
Hey Everyone.  I picked up a new R10 with the Gtx 3080 3 months ago.  The card has since failed (confirmed through support and testing).  Issue is apparently with the card.  Support advises that there are "no replacement cards available" at all and there are no options for refund or replacement.  The system will work periodically to run mobile style games, but anything more advanced causes an immediate CTD and turns the Mouse/Keyboard off.  It's souring me a bit on my first alienware purchase, but I'm staying optimistic. Looking to see if anyone has similar issues and, if so, if anyone has come up with a workaround to this failure.  Interestingly enough, the device shows as a failure on the Dell site tests, however, under "resolve" it states that there are no issues with the device.  At this point I would be happy if I could just get the card to work as well as my old 1080 did.
