Testing notes
Benchmarks were conducted at 1280 x 1024 4x AA 8x AF and 1600 x 1200 no AA 8x AF. These are likely resolutions and image-quality settings for mid-range cards and we've run the cards through three popular games. A lack of memory bandwidth will hurt the GeCube card when compared to the Sapphire dual-GPU model. We clearly understand that the asking price of dual-GPU cards is considerably higher than the SRP of single-GPUs', and we'll tot-up the value-for-money aspect when we take a look at the cards' HEXUS.bang4buck.
As always, we ran each benchmark three times and then calculated the arithmetic mean. If any of the three results looked erroneous, we threw all three away until we could collect a set that was within a margin of statistical error. We report any major attempts needed to get three reliable results, of course. Apart from that, things are as noted on the graphs and in the graph commentary. Want to know more?
