If you have the money to spend why not spend it? On the flip side, have you ever ridden a mountain bike before? It may not be your thing.
For that amount of money you can get a great hardtail or a decent full suspension. Your local trails should help you decide what type of bike. Age might also be a factor. At 34 I can't do long rides on a hardtail. An easy way to see if you will like it, is borrow a friends bike or demo a bike from a LBS. Be sure to leave some money in the budget for helmet, shoes, hydration, gloves, etc.
