When it comes to gaming performance for your dollar, the ATI Radeon HD 4870 is currently unmatched. If that's not enough reason to snap this card up, we don't know what is.

Sapphire's Radeon HD4870 offers an impressive amount of graphics power at a modest price, and while it won't appeal to the power gamer, it's more than enough for most users.

It's been a long wait but we're very happy with the results of ATI's new graphics chip so far. Although it's not up to the challenge of NVIDIA's GTX or Ultra cards, there's potential for a promising high-end version in the future. Until then, the Asus HD 2900 XT is an excellent value-for-money card.

It's the most powerful card on the market and trumps its closest competitors, but it's also the most expensive. If you want the best frame rate possible from a single card though, this is the one to buy.

The Radeon HD2900XT has been a long time coming and in our eyes, it was well worth the wait. This card offers everything the competition offers and a touch more. Unfortunately we were unable to test DirectX 10 games this time, but we expect to see some promising results.

This is by far the hottest card on the market and will continue to do the job well into the future. If you want the best performance then this is the card to get.

The Golden Sample offers excellent performance at a competitive price, making it ideal for users who require high-end gaming.

There's no doubt this is the best card on the market. Every feature is leaps and bounds ahead of the competition from ATI, at least until they release their own DirectX 10 capable card, the R600. The real question is whether to buy this card, or wait until competition brings the prices down and game developers actually start making games that utilise the new improved features.

This innovative package really takes the pain out of finding and configuring an SLI setup. Great for serious gamers.

Some of the best value for money available, it can run most modern games quite comfortably without denting the bank balance.

A great performer for the cost, definitely one to look out for if you want bang for your buck.
