Next up we have a few more game tests to see how well performance scales with Radeon HD 6870 cards running in CrossFire mode.

In the remaining tests, we again see the PowerColor Radeon HD 6870 2GB Eyefinity 6 Edition cards offering solid performance and good scaling when running in a two-card CrossFire configuration. In some cases, like Metro 2033 and Alien vs. Predator in particular, the games when from a just playable 30-ish frames per second, to a much more fluid and smooth 60-ish FPS.

To better show just how much the performance in each game improved, we’ve summarized them all here. Upgrading from a single card to two cards, with the applications we used for testing, resulted in a minimum performance increase of 82% and a max of 99% (a 100% improvement is the theoretical maximum, which unlikely to happen due to the overhead associated with the various complexities of running a multi-GPU setup).

Now that we’re clean that a pair of Radeon HD 6870 cards running in CrossFire can offer some serious performance using a single monitor, let’s see how they behave with five screens connected...

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
