Which of these routers to get?

im looking for a new gigabit ethernet router and iv come down to these 2 models by trendnet. the two differences is the frequency bands and the price. if someone could please explain the importance of the freq band differences of these two id be greatly appreciated... this will ultimately make the difference in which i buy. the more expensive has alot more freq band settings than the other one which is roughly 30 bucks cheaper after taxes and all so just want to know the importance of this. im hooking my gaming pc with direct connection while having 2 other laptops + ps3 hooked up by wireless so which would be best? i also to port forwarding for torrent downloads if that will be effected by either router. thanks!
