So I have the MSI Z87-G45 Gaming motherboard and was reading the product page and MSI claims that you get a performance boost when using an MSI GPU with an MSI mobo. My question is does anyone know how much of a difference this actually makes? I plan to upgrade to a GTX880 when they are released and am trying to decide now which model I will actually get. It's between the EVGA GTX 880 SC ACX cooler or the MSI GTX 880.
