"As you'd expect, then, the 4850 is a vastly superior performer to the Sapphire Radeon HD 4670 512MB. This, though, is to miss the point, since the Sapphire Radeon HD 4670 512MB's real competition is the likes of the nVidia 9600 GT and the older ATI Radeon 3850. And here, the 4670 acquits itself extremely well, comfortably beating the 3850 by 13% in Crysis testing, and by 15-18 percent in Quake Wars and Stalker. Only in Company of Heroes did the 3850 manage to finish marginally ahead. The 9600 GT also put up a losing fight, although it'll be interesting to put up the Sapphire Radeon HD 4670 512MB against one of the newly enhanced 9600 cards.
With Christmas only a couple of months away, we can expect a number of budget cards to rewrite the sub-£75 graphics card market, but right now the Sapphire Radeon HD 4670 512MB is the touchstone, and is certainly a superior deal to the 9600 GT and 3850 Pro. And while there are cheaper versions of the 4670 available, Sapphire has given ATI's HD 4670 the VIP treatment to make the best sub-£75 deal we've seen yet."
