Shadow the 212 is recommended to most because it allows overclocking to 4.2 with no sweat (which most people are more than happy with) or depending on ambient temps 4.5ghz is usually quite achievable on it. With ambient temps of 33c I was able to hit 4.5ghz I might try overclock it again see how far I can push it in the middle of winter here so I might almost have what anyone in the eu considers a fine summers day temperature as the ambient (16c is classed as freezing cold here).
