Sapphire HD5670 Ultimate Edition Crossfire X Review

When testing the Sapphire HD5670 Ultimate in a Crossfire configuration we feel it is important to use a processor that the buying public would be using in this specific sector. We could easily slot in an Intel high end Extreme Edition CPU, but its not a very realistic configuration so this time we opted for the 6 core AMD 1055T which we overclocked without a hitch (or the need for extra voltage) to 3.7ghz. If you want to see how to do this for yourself, check this out.

We normally include a broad cross section of graphics cards in these reviews, but we have already ran comparisons against the HD5670 in the past, today we are concentrating on Crossfire X performance gains if you add an additional card to a system.

While we previously tested the HD5670 at 1280×1024 resolution, today we will test at the native resolution of our 24 inch screen (1920×1200) and crank the image quality when possible … if you are spending twice the money you need to be seeing noticeable improvements to make it worthwhile.

All the latest bios updates and drivers are used during testing. We perform under real world conditions, meaning KitGuru test all games across five closely matched runs and average out the results to get an accurate median figure. We mix and match various games across our reviews to try and keep our regular readers interested – no one wants to see the same handful of games used in every review.
