Faster, cooler and for only another £13 on top of the price of the vanilla AMD Radeon HD 7870 - why wouldn't you go for the new Sapphire HD 7870 OC Edition?

Sapphire has waded in first with its take on AMD's latest HD 7000 series card, the Sapphire Radeon HD 7950 OverClock edition.

Spot the difference between this graphics card and the HD 5770

This budget graphics card is a Llano-compatible upgrade on its older sibling

A quality HD 6950 graphics card with good overclocking capabilities

A good value GPU that goes toe-to-toe with the GTX 460

Is the graphics card the perfect partner for high-end AMD CPUs?

A good value all-purpose GPU with integrated basic TV tuner

A capable low-end card, but struggles at higher resolutions and with DX11

Can an overclock make this card more desirable?

Sapphire's Flex Edition entry into the 5770 fray is as solid and competent as you'd expect from one of the key historical ATI partnerships. It's as roundly well-featured as any other 5770 out there, boasting HDMI, DisplayPort and two DVI-out ports, and the chunky aftermarket cooler is reassuring in its girth.

AMD's Radeon HD4770 is a bargain bucket powerhouse, but is it the best?

Now that AMD has found its way back on top, in the graphics sphere at least, it's NVIDIA's turn to go for the jugular. And it's NVIDIA's flagship GTX 280 that AMD is seeking to bury with this exclusive Sapphire release, the long-awaited 4850x2

It's early days for the Radeon HD 4670 chipset, so it's no surprise to find that Sapphire's first take sticks closely to AMD's reference design.

Can't beat them? Then undercut them. That's the message from AMD about graphics cards. It's the same logic that helped the firm establish its CPU business, and it could work just as well in the world of video. With so few games engines on the horizon that are going to test current hardware, it's hard to argue with that logic.

My head's all in a whirl, the graphics market is changing afore my very eyes. In the final days of the big DX9 cards, all the competition between the red and green camps was about the high-end. It was assumed that if a company bags the high-performance crown, then that would have a trickle-down effect on the rest of its range, urging punters to hurl their cash behind the top team in the low and mid-range sectors too. Now, with NVIDIA having the top end sewn up that's it, right?

Going under the new moniker of 'Atomic', rather than the Toxic title that Sapphire's first X1950 wet-ware was sold under, the Asus EN9800 GX2 Quad SLI is a new revision of AMD's standard reference 3870x2. So how does it fare against it's warmer brethren? Actually, it's not much different.
