am going for a asus gtx 460 1gb . Normal cooler with out the direct cu thing . thats a reference model eh ?
The Asus model you listed in your first post is the high-end Direct CU copper heatsink model with a factory overclock ("TOP").
I have found Asus to be one of the best brands with high quality components, even in their reference models (which are designated with the "ENG"). Even the reference models promote voltage overclocking, so they need to use high quality components throughout to guarantee good overclocks with voltage tweaking.
