Tweaknews posted a review on the HIS Radeon HD 5770 Videocard

The HD5770 seems to be a sweet spot for the gamer who wants a decent card that would still be a performance upgrade even over a HD48XX card and achieve the sought after full DX11 support. With HIS's version, the card come right out of the box with a full DX11 game and allows the gamer to buy the card, download the free game and actually use their card without much of a wait.
