What graphics card should you buy? Our 15 best graphics cards in the world article is regularly updated.

PC gaming is currently going from strength to strength. Upcoming games such as Bioshock Infinite and The Darkness II look set to raise the graphical bar even higher, and recent games look phenomenal on the PC. Just compare Skyrim running on a decent PC and graphics card to it running on an Xbox 360 or PlayStation 3 and the difference is like night and day. Plus as the consoles stagnate due to their ageing technology, it's something that's only set to continue.

In order to experience such games at their best, though, you're going to need to ensure you have a machine that's up to the task. And by machine, we're primarily focusing on your graphics card.

So welcome to our best graphics card article – it's constantly updated with the very latest best graphics cards.

It's the graphics card that does the serious work when it comes to rendering your games, and the more effects and higher resolutions you throw at it, the more is asked of that graphics card.

It's important to pick your graphics card so that it works well with your display, or displays. There's no point, for instance, trying to power a 30-inch screen with the likes of a GeForce GTS 450.

By the same notion, running a standard 20-inch screen with the likes of an AMD Radeon HD 6990 won't begin to tap into the card's power.

As a quick rule of thumb, whatever you spent on your screen, you're going to want to spend a similar amount to power it. Roughly.

The question is, which one of the many graphics cards out there should you actually spend your hard earned cash on? Here TechRadar highlights the top 15 cards worth considering. We cover the notable cards from the last generation, the best all-rounders for most PC gamers and the £550 monsters that can handle multi-screen outputs.

In this guide we'll let you know what's hot, what's cool and what are the fastest GPUs available right now and worthy of your time.

Best of all, because we're now enjoying the second generation of DirectX 11 hardware, every card we look at here is capable of rendering the latest, funkiest DirectX 11 games.

So how does your graphics card stand in our countdown, and is it time for an upgrade?
