The steak will be tender and juicy, since searing it at such a hot temperature locks in most of the juices, similar to the way a wound is cauterized.
I only recommend you do this if you have a VERY well ventilated kitchen, as the amount of smoke generated will surely set off any smoke alarms in your house otherwise.
Sidenote: Why is it that a lot of modern kitchens don't have properly ventilated hoods that actually vent outside? It seems ridiculous that most of the hoods over stoves nowadays just recirculate the air back inside. When I want to cook, I want to cook, damn it!
