We took a hard look last week at AMD’s Radeon HD 6870 and HD 6850, and in the end, were left impressed. The FPS/$ ratio was superb, as was the feature-set. How do things look when the same cards are tossed into a CrossFireX setup? Well, AMD claims an up to 1.99x gain in certain games, so let’s see how reliable that figure is.

For those looking for the ultimate fill of zombie killing, look no further than Dead Rising 2! The game looks great, has a lot of “realistic” zombie’s, and is a lot of fun to play. To test, we take a quick run through the mall accessible not long after beginning the game which lasts about 2 minutes and follows the same path each time.

In the introduction to this article, I mentioned that multi-GPU game support is better than ever, but here’s a perfect example of when that’s not the case. The results were all over the place, and after checking in with AMD, the reason is simply due to the fact that a CrossFireX profile is not yet created for it. That will change soon, however, which should make these results obsolete.

This does raise the fact that even today, multi-GPU is not perfect, and it’s never guaranteed that a game is going to cooperate with some of the latest games out there. AMD has been rather fast in getting CrossFireX profiles out the door, but this is one of the rare exceptions as the company didn’t have access to the game prior to its launch, and of course, this Radeon 6800 launch delayed things even further.
