performance wise both should be the same. about the cooler you might need to look around for reviews that actually test the card that you mention. but i bet both will perform just the same in term of cooling performance however the noise generated from the fan might be a concern.
Thank you for the reply
I change my mind regarding GTX 670 Vcard. And, I also found out that Inno3D have some issues with their cooling performance, so Palit would be the better choice IMO.
I'm going with Palit GTX 680 4GB for future proof.
well congratulation on your new card. happy gaming
