We already know that two Radeon HD 6850s in CrossFire are fast. However, based on our recent exploration of micro-stuttering, there's a fair chance that enthusiasts sensitive to this phenomenon might not be satisfied with the way a pair of these cards behave. If you already know this doesn't affect you, then you're in the clear.

The GeForce GTX 570 and Radeon HD 6970 offer exceptional performance for around the £270-mark. Both cards perform slightly slower than GeForce GTX 460 cards in SLI and Radeon HD 6850 cards in CrossFire, but they do so without the hassles associated with a multi-card rig (including power, cooling, motherboard slot spacing, and in some cases, micro-stuttering).

Two Radeon HD 6870 cards in CrossFire and two GeForce GTX 560 cards in SLI are very powerful, capable combinations. Just keep in mind that, if you plan to employ resolutions above 1080p with anti-aliasing enabled, you may want to consider boards with more than 1 GB of RAM.
These solutions are demoted to honourable mention status based on Micro-Stuttering And GPU Scaling In CrossFire And SLI.
