Take MSI GTX460 1GB HAWK
It's a pretty good card with 2 fans instead of 1, but that might make it more noisy. The ASUS card comes with CUCore technology which cools the card wsithout the need for an extra fan. Both cards have voltage tweak technology so it really doesn't matter
The ASUS one is cheaper though, so I'd go for that. THe ECS version also has 2 fans but comes at a higher clock speed.
