We really like AMD's Radeon HD 7970. There's really no reason to pay extra for a similar-performing GeForce GTX 680 unless its 55 W-lower thermal ceiling is necessary in your small form factor enclosure. In that case, spending more for better efficiency is something we can get behind.
You might be able to find a Radeon HD 7970 GHz Edition card selling in the £350 range. If you do, that'd be a good buy too. But for the money most GHz Edition cards are currently selling for, we'd skip them. As they stand, the Radeon HD 7970s are already pretty overclockable, meaning you can coax much of the performance difference out of a cheaper card anyway.

Honorable Mentions over £350:
Assorted Multi-Card Configurations
The Radeon HD 7970 delivers such impressive performance that we find it hard to recommend higher-performing (but sometimes-inconsistent) multi-card configurations for more money.
We'll call out some of the most promising options, though, mostly for folks with one of these cards already installed: two Radeon HD 7850 2 GB cards in CrossFire, two Radeon HD 7870s in CrossFire, two GeForce GTX 670s in SLI, and finally, two Radeon HD 7970s in CrossFire.

Nvidia's GeForce GTX 690 is one of the fastest graphics card in the world. It's essentially two GeForce GTX 680s on a single PCB, with a slightly lower core clock and a 300 W TDP. The company sets this card's MSRP right around £800, which used to be two times higher than a single GeForce GTX 680, but is now a little pricier. Still, that's not a bad deal if you were planning to go with a pair of GTX 680s in SLI anyway. Although it used to suffer from availability issues, the card can be found for its £800 launch price without much trouble.
For all intents and purposes, AMD appears to have dropped plans for an official dual-GPU Radeon HD 7990 to compete with Nvidia's flagship. This hasn't stopped a few companies from releasing dual GPU-equipped Tahiti cards. PowerColor currently has one selling for £700, but that's more expensive than a couple of Radeon HD 7970s operating in tandem. It looks like Nvidia will keep the single fastest card title this generation.
