Sapphire is best know for taking an ATI product, and making better. It's rare that an AMD partner takes engineering into their own hands, a produces a self-made product. What's impressive is that they've decided to do so with a dual-RV770 Radeon HD 4850 X2 as their latest evolution in graphics cards. Benchmark Reviews compares performance against the GeForce 9800 GX2, CrossFireX 4850's, and the Radeon HD 4870 X2 to name a few, but add a collection of todays hottest video cards to make sure the Sapphire 11139-00-40R receives a workout.
