Looking at the options for GTX 570s on that site (please list all the options if there are more than the EVGA and ASUS), I would go with the ASUS with the DirectCU cooler (its very cool and quiet). But if that's too much, then EVGA are known to make their cards well and the Nvidia reference cooler it uses is pretty decent.
good good - thanks for that - i think that is the one i will suggest to him
