Legit Reviews checked out the ASUS MARS II Limited Edition card at BlizzCon 2011. This exclusive dual-GPU GeForce GTX 580 card costs a whopping $1,500.
Of course the $1500 card, which is slightly more than the $1300 "regular" MARS II was tethered to the desk drawing a pretty large crowd. The Limited Edition MARS II configuration has two factory overclocked NVIDIA GeForce GTX 580s with 3GB of GDDR5. The fans you see are two 120mm that are coupled to a special form of cooling the beast. There is a 21-phase Super Alloy Power manager that improves performance and extends the card's lifespan with cooler operation.
