Stiff competition, then, but the Radeon HD 4800 series really is up there. As it happens, the 4800 was AMD's own return from the brink after the calamitous Radeon HD 2900 and the mediocre 3800. But more than that, it was the thinking man's GPU. Not the fastest you could buy, perhaps. But easily the most efficient performance GPU in terms of both power consumption and return on investment. Yes, Nvidia's GeForce GTX 200 cards were quicker. But nowhere near as much as you'd expect given the added cost and complexity.
