Notes

Five cards all costing between £100-£145, benchmarked at 1,680x1,050, 1,920x1,200, and 2,560x1,600 resolutions, along with decent image-quality.

We've noted how much better the cooling is than the reference design, but with an SRP of £139.99, pricing is almost at Radeon HD 4870 512MB levels.
