If you're a firm believer in the 'behemoth GPU', Sapphire's Radeon HD 4850 x2 will do little to sway your opinion. While it performed solidly enough in our benchmarks, it failed to match NVIDIA's single-GPU GTX 280 offering. Nevertheless, it remains a good option for any self-respecting Radeon fan with a penchant for monitors.

Those who want the absolute best settings on in their DirectX 10 games (such as the soon to be released Crysis) may want to wait for the next generation of cards, but for now this card is the best available on the market.

For mid-range gaming, the P860 is a fast choice. It won't produce super-smooth frame rates in the latest games, but it will produce playable frame rates in most games, and those frame rates will still be better than what most competing 8600 GT-based cards can achieve.

This card will handle any DirectX 9-based game on the market, but it's still not as fast as cards based on NVIDIA's high-end 8800 GPU in DirectX 10-based games. However, DX 10-based games are still playable with this card at resolutions lower than 1920x1200 and is a good value card.

The Sapphire HD3870 is ATI's next generation of GPUs, superseding the HD2000 series and challenging NVIDIA's 8800 GT cards for a place in the mid-range market.

This GPU is one of the best value-for-money options currently out there, but the additional cost of buying this pre-overclocked version may not be worth the few extra frames and the additional heat.

You can forget the old GTS models because this new card, based on the G92 GPU, is a far better choice, even if it has some limitations.

This is a standard graphics card that's suitable for not-too-serious gaming, and for watching Blu-ray movies.

This is a slightly-better-than mid-range graphics card that's suitable for playing DirectX 9-based games at high resolution and detail settings, and DirectX 10-based games at mid-range resolution and detail settings.

At last ATI has made a comeback of noteworthy proportions with this new board. Our look at the Sapphire Radeon HD3870 X2 has left us impressed, even if we're a little concerned with the limitations of this hardware-doubling technique.

Overclocked GPU and memory components aren't enough to supply fast frame rates for DirectX 10-based games, but if you want a modern card for your DirectX 9-based games, and also a card that's HDCP-ready, then this HIS model is as good as any.

Two GPUs on one card sounds promising in theory, but this card didn't shine in all our tests. It does have four DVI ports though, so if you've always wanted to run four monitors off one PC, then this is the card for you.
