Welcome to the Digital Foundry 2015 graphics card upgrade guide! It's an extensive effort that attempts to address all elements of the most important upgrade you can make to your games PC - the GPU, or Graphics Processing Unit. We're attempting to cover everything here, starting with the basics including the actual upgrade procedure and the importance of the surrounding components in your set-up, all the way through to the extreme in-depth analysis we put into road-testing every new graphics card that comes our way.
The topic at hand is vast, so some element of simplification is required. To that end we've split graphics hardware into three segments - entry-level, mainstream enthusiast and top-tier performance, covering budgets from £80/$130 all the way through to £430/$550. We'll have benchmarks from the latest wave of DirectX 11 games on all contenders, along with hints and tips on improving frame-rates with the least impact on overall image quality. Our primary focus here is in delivering a gameplay experience on par with or better than that offered by PlayStation 4 or Xbox One.
