Hi, I'm building a new system with a 680 and the store I'm purchasing from has an ASUS 680 at the same price and with the exact same stats as an EVGA 680 I was going to purchase. The EVGA has to come in from EVGA and would take up to two weeks, while the ASUS is in stock atm. I have an EVGA currently and I'm very happy with it, my question is if there is a significant difference in terms of quality in video cards between EVGA and ASUS that I should consider when deciding between the two. Also, both have a 3 year warranty. Thoughts?
