It's not woefully out-matched, but those that can afford the shift up to a 1GB GTX 460 will reap the benefits, whilst a £20 saving and plumping for the 768 version produces similar performance.

AMD needed to do something special to unseat the impressive power and value offered by the GTX 460. Importantly it hasn't managed it. Better performance or a lower price would have helped things here, but as it stands, this is hopefully no indication of what is set to come.

Nvidia's Fermi finally goes mainstream

The FTW Edition, despite the rather ridiculous, MMO-inspired 'For The Win' acronym, is still the fastest out-of-the-box GTX 460 card around. It churns through the benchmarks beautifully, and in SLI trim the performance will be incredible.

As the very cheapest of the HD 5770s we've tested, XFX's offering grabs our interest. Shop around, and you can have one of these for as little as £116 – that's a whole £35 cheaper than Sapphire's offering, with its four-screen EyeFinity capability.

The 5770 is, in general, an odd prospect right now. On the one hand, you get functionality that supports DX11 and its suite of goodies, such as hardware tessellation and improved multi-threading support. However, as the first mid-ranger with true DX11 capability, we have to remind ourselves that it's just that: a mid-range card. The extra features offered by DX11 require a resource overhead, and when you add in anti-aliasing and anisotropic filtering, that's an awful lot for a sub £150 card to do.

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.

Pre-overclocked cards are always a bit of a gamble, and the penny turns on a number of factors. How overclockable is the GPU in the first instance? Does it offer much headroom to the manufacturer? The same goes with the memory. And the price of overclocking at a hardware level, as we all know, is heat generation, which often means an extra premium for a special non-standard cooler.

This TOP Edition's overclocked loving though does give it the edge, but the cost here too is going to make things tricky when you're making your buying decision. It's still a good card, but it's really only as good as the AMD offering. Unfortunately then for NVIDIA it's not quite the card-killer that it might have hoped it would be; maybe worth a look in SLI but for now it's still far too close to call definitively.

The only real hope for the 768MB versions of NVIDIA's latest card, the GTX 460, lies in these pre-overclocked, such as EVGA's Superclocked and Asus' GTX 460 768MB TOP.

We've already seen the stock GTX 460 768MB, and now it's the turn of the overclocked cards in the shape of Asus' GTX 460 768MB TOP edition.

The brand new GeForce GTX 460 has turned up in two rather different flavours; the full version like Zotac's GTX 460 1GB and this the paired-down, slightly cut-price, 768MB version.

Barely a month after Nvidia's last GF100 graphics card, the GTX 465, struggled out the stable door another new graphics card, the GTX 460 has turned up to steal its thunder.

If it's hard to justify the £300 price for a stock version of the card, though, is the 50MHz overclock Zotac has given its GTX 470 AMP! Edition worth an extra £70?

Unbeatable performance for an AMD –based card, but too expensive to be taken seriously

If, and only if, you're the kind of person who enjoys torturing silicon until it screams by increasing clockspeeds and voltages purely for the hell of it is the Matrix HD 5870 the card for you.
