Rounding out its Radeon HD 6000 series, AMD this month launched three sub-$100 graphics cards; the $55 HD 6450; the $79 HD 6570 and the $99 HD 6670. Despite being low-end options, all three support Eyefinity and are of course, extremely power efficient. Let’s see if they also have the gaming performance to boot.

Just Cause 2

Just Cause 2 might not belong to a well-established series of games, but with its launch, it looks like that might not be the case for long. The game offers not only superb graphics, but an enormous world to explore, and for people like me, a countless number of hidden items to find around it. During the game, you’ll be scaling skyscrapers, racing through jungles and fighting atop snow-drenched mountains. What’s not to like?

Manual Run-through: The level chosen here is part of the second mission in the game, “Casino Bust”. Our runthrough begins at the second-half of the level, which requires us to situate ourselves on top of a car and have our driver, Karl Blaine, speed us through part of the island to safety. This is a great mission for benchmarking as we get to see a lot of the landmass, even if some of it is at a distance.

The top two cards could handle the settings we use for Dirt 2 at 1680×1050, but being a much more intensive game, Just Cause 2 made a total mockery of them.

After decreasing the graphic detail quite a bit, each card was able to handle the game quite well overall. We topped out our settings with both the HD 6570 and HD 6670, so choosing the latter card will simply give you better performance, not improved detail. For the lowly HD 6450, the resolution had to be decreased all the way to 1024×768, with most of the detail turned all the way down.
