For some time now ATI has been planning a refresh of their 4870 and today that product reaches us in the form of the Radeon 4890. The 4890 is now ATI’s fastest single GPU solution and many would think that Nvidia need a refresh of their top end card, the GTX 285, to compete with ATI. This is not the case though as Nvidia feel they have a great value competitor for the 4890 with their new GTX 275.
Today we will be putting a selection of 4890s up against the GTX 275 in the latest games at resolutions up to 2560x1600. We will also run each of the cards through a selection of GPU computing tasks as well as completing our test suite with some CrossFire tests and overclocking/thermal performance.
