Based on price and my personal preferences I have it narrowed down to three choices, but cannot choose. Noise is not that big of a deal and I am definitely not worried about power consumption. The three cards are listed below.
I know all of those card are perfectly capable, but I would go with the sapphire because, I THINK, that the XT means that it has the new tahiti gpu or is a stripped down version of the 79xx's. But either of those 3 would be a good choice.
