Sapphire and MSI have rolled out revamped editions of AMD's ATI Radeon HD 5770 graphics card.
Sporting Radeon HD 5750-like coolers, the new-look 5770s suggest a revised reference design by the folks at AMD. Presumably an attempt to lower manufacturing costs.
We've yet to see any real-world performance numbers, but heat-conscious users may be deterred by the fact that AMD's new dual-slot cooler won't exhaust hot air from the rear of a chassis.
Despite the change of cooler, the cards themselves don't appear to have been altered. Both the Sapphire HD 5770 (above) and MSI R5770 (below) feature stock frequencies of 850MHz for the GPU and an effective 4,800MHz for the 1GB of GDDR5 memory.
We've yet to see either of the cards filter through to retail, but we expect them to surface at around the £120 - £130 mark.
