ATI Radeon HD 5870 Eyefinity 6 Performance Review

While the ATI Radeon HD 5870 Eyefinity 6 Edition supports up to 6 displays, we are going to be performance testing in the more popular 3x1 configuration. We are going to get a the heart of the video card and see if the 2GB of memory on Eyefinity 6 is really beneficial in Eyefinity resolutions with single GPU as well as CrossFireX.

Evaluation Method

We evaluate what each video card configuration can supply us in terms of a playable gaming experience while supplying the best culmination of resolution and "eye candy" graphical settings. We focus on quality and immersion of the gameplay experience rather than how many frames per second the card can get in a canned benchmark or prerecorded timedemo situation that often do not represent real gameplay like you would experience at home. Then we will follow with apples-to-apples testing in with minimum, maximum, and average framerates.

Test System Setup

We will be using a Gigabyte EX58-UD5 motherboard, an Intel Core i7 920 Overclocked at 3.6GHz, and 6GB of Corsair TR3X6G1600C8D Dominator DDR3.

While it might be "overkill," we use the Core i7-920 processor at 3.6GHz in an attempt to prevent our evaluation from being CPU limited. Obviously, we make every effort to not use CPU limited games for video card evaluations, but the i7-920 at 3.6GHz seems to put many peoples’ minds at ease when it comes to that subject.
