Hey, should i get the n85, n79 or nokia 5730?

I heard the n85 has horrible built quality, so im a little scared if i get that phone.Also, the 5730 camera may not be up to my expectations and the n79 seems to be a very average phone.I focus on gaming, taking pics, watching videos, and definitely play a lot of games.I know i have asked it once but please help me answer it again coz i added in more details.tks
