Back in 2009, ASUS launched their 1000-piece limited edition mammoth "Mars" (2 x GTX285 on a single card) and took the performance crown over then GPU leaders NVIDIA GTX295 and AMD HD5970, albeit at a significant price premium. Two years later today, we do a mini review on the world's fastest single graphics card equipped with two GTX580 Fermi cores - the ASUS Republic of Gamers Mars II 3GB.
A very big box
Like its predecessor, the ASUS ROG Mars II has limited production run of 999 pieces (ours was the "529th").
GTX 590 (2 x GTX 580)
2 x 1.5GB
2 x 1.5GB
On the triple slot I/O shield, we have two DVI-D ports, a HDMI and a Display Port interface on the card allowing for up to 4 display outputs.
At the side of the card, there are 3 x 8 pin PCIE power connectors delivering up to 450W of additional power. There is also a red-backlit button to override and trigger 100% fan speeds on the two huge 120mm fans in the cooling system.
ASUS has thoughtfully bundled a "PCI-E sustainer" to protect the motherboard and to aid mounting in obtuse cases.
