Does it have a reference cooler? If so, then that means all the cards have that cooler regardless of company. There are few companies who release few cards with non-reference coolers. Those cards are typically a lot better (better power components, regulation, caps), quiter, and are a bit more money though.
I checked my FPS (ingame, the green button-thingy..) and it was was around 200 FPS the whole time, 220 was the most, but I have not had any problems like you did.
(To be honest, I don't believe I really have 200 FPS..what's up 'bout that?)
