The first salvos of the this years graphics card showdown have been fired, but where does your graphics card stand? We've retested every major card from the last eighteen months and beyond to help you decide if now is the time to upgrade.

Batmobile? Oh that. Yes, we can see why you might think that but it's actually ATI's new Radeon HD 5870 1GB graphics card. The new model is based on the company's next generation Cypress GPU, but is it worth snapping one up right way? To the Batmobile!
