Very nice, but I'd daresay you could do the same process with a much less expensive cut of meat. I'd suggest the next time to use a skirt steak, really gamey, very fatty, and it'd be much more giving in a braised/stewed application such as that. Ribeye is definitely a sear/grill cut, to cook it so well done is a crime to the cow that died.
What's in the marinade btw?
