It's looking like a familiar X2 story, and the Radeon HD 4850 X2 scales as well as the Radeon HD 4870 X2, providing near-double the performance of a single Radeon HD 4850. Who'd have guessed?

At resolutions of 1,920x1,200 or below, though, we find the Radeon HD 4850 X2 to be roughly on-par with BFG's far cheaper GeForce GTX 260 OCX MAXCORE. Raise the resolution to 2,560x1,600 and the Radeon HD 4850 X2's 2GB framebuffer proves its worth by leapfrogging the NVIDIA competitors.
