I think eVGA Superclocked GPUs uses NVidia reference cooler and the ASUS one uses DCUII cooler. So in terms of thermal solution, ASUS one is better. Personally I would take the ASUS one but yes eVGA has really nice support and warranty. It's up to you. Also the 6870 above seems to be a really nice deal, if you can get the 6870 in $160 (and $160 is lower than those 560s), go get the 6870.
