Look with the EVGA cards you aren't going to get cooling that is going to lit the world on fire if you wanted cooling you would go with brands like ASUS, MSI, and GIGABYTE. You wouldn't with EVGA even there Signature 2 cards which I would prefer from EVGA are still quite reference. I would say no its not worth it the more expensive card may have more ram which you don't need more then 2 gigabytes unless you were going to get into mods with SKYRIM or it could be factory overclocked which isn't necessary either. I have this card. http://www.newegg.com/Product/Product.aspx?Item=N82E16814125423
And the only reason why I purchased it was because of the cooling and peformance the card receives I would of gone with the ASUS one but it was more expensive and I was running on a strict 400 dollar budget at the time. So my opinion save your money get the cheaper of the two enjoy the two games you get with them :P and enjoy your card.
