Imagine a graphics card weighing 5.25 pounds with three (yes, three) 8-pin PCI Express power connectors. Now imagine this card taking up three PCI Express slots and almost sucking the life out of an 850W power supply.
That may be one reason Asus named this card after the Roman god of war. It's probably the most powerful single graphics card we've tested, but that power comes at a substantial cost. You'll need the right type of motherboard and case, too—one where you can install a three-slot-wide card that's 12.25 inches long and 5 inches tall.
Did we mention that it also costs $1,400?
