Agreed. While GTX-1080Ti has long been the price point for simulations,
Dell's going to bite you back if you start doing things to their machines.
The contract that locks you into Dell is probably built on incentives like
discounts and a deluxe warranty, which you will be forfeiting if you change
the hardware (or OS). I'd talk to your acquisitions people (start with
your department administrator, ask him or her who to speak to, and go from
there). See If you can get a special dispensation and start constructing
your own machine. Gaming systems companies will build you a desktop with
dual GTX-1080Ti cards no problem, but they may be politically impossible
for your acquisitions department to do business with.
