Is this the best GPU for the price point ($270)?

Corsair CX series is on tier 3, which isn't a very good PSU, I'd suggest something like

Which is tier 1 according to the tier list, I have used SeaSonic PSU's (not that particular model, have been the more expensive X Series) and they are very good brand.
