Ok I finally got my evga 780's acx model...I got this version due to the overclocking capability of this particular model...However one card will overclock to 1248mhz 100% stable in all benchmarks and games and has asic score of 92...my other card wont even handle any type of overclock and has a asic of 63...should I return the card since I have option from Bestbuy and see if I get lucky with another card or just keep it....I just want some feedback before I go through hassle of taking card back...thanks
