Without a shroud, Sapphire loses a lot of real estate to create an attractive look for the HD6670 Ultimate. While fins aren't typically appealing, the all black finish, including the base of the heatsink, helps to appearance of the card, especially with the tribal logo that will peer out windowed cases. The upside to the passive cooling system is absolute silence, and the card does a good job keeping cool even when we throw the top titles at it.
The Ultimate HD6670 shows quite a range between minimum and some impressive maximum rate, which translates to a quite respectable average FPS for an entry-level card. Even at these high settings and full high-definition output, games were playable despite a few low peaks here and there; with settings tuned down a bit, you would have no problems whatsoever. The HD6670 isn't the best performing card on the market, but being a silent card that’s not the goal. This is perfect for someone who wants to play their Sims 3 at a good resolution without problems without being distracted by a noisy PC. In that situation this card would outperform everything on our charts, silent is silent.
