I'm going to go with; Singapore is a hot climate, so get the EVGA card that vents heat outside the case. How's that for a rationale? There's also a couple guys on these forums that always say never to get the Palit cards, for some reason. Maybe they know something. Everyone likes the EVGA's.
I think that the Palit is better because it's got two fans, 2MHz extra over the EVGA, not sure if that even matters,
it's got a custom cooler different than the standard.
