So my brother wants to build a pc and he doesn't mind my 7950's acoustics and coil whine. So I am gonna hand that over to him and get a new gpu, from nvidia this time, I am just done with AMD. I was gonna delay my purchase due to the watch dogs release happening in 2 weeks but I found out about the promotion nvidia is doing. What better time to get a new card? So I started looking at my options and figured that a GTX 780 would fit my performance requirements (I am on 1080p and won't move in the near future as I have no room for second monitor). However the retailers I can get a GTX 780 from here (in Greece) don't have the promotion except from one, which only has the Asus version. While I was planning on getting the SC ACX one, Asus is also an option for me now. So which one is better? Keep in mind I am realy concerned about acoustics as I am a silence freak.
