You'd be able to get 100% cheaper (half the price), for only like a 10-20% drop in performance, which you probably won't be able to notice anyway, as that 10-20% performance is way in the overkill range (like you would NOT be able to see the difference between 160fps and 200fps in a game).

But then again, as long as your happy with it, and have plenty of money, then go ahead.
