Depends on your route choice. If you go through San Angelo, Big Spring through the shorter route that is if you're a decent navigator and you don't mind driving through the desert, I mapped it out to 744 miles..... Or you can take Interstate 35 to Oklahoma City and take the 40 to Vegas Junction NM then take 84 to the 85/I-25 to Las Vegas NM after that hop onto the 518 and take it all the way to Taos and its mapped out to 957 miles
