This time around we have a successor to the MARS - the NVIDIA version that combines two top-level GPUs on a single PCB. The new ASUS MARS II we are reviewing today is a pair of binned GTX 580 GPUs paired together for full-time SLI and built with a limited edition run of 999 units. In many ways the MARS II and the ARES share a lot of traits: custom designed cooling and PCB, a unique aesthetic design, limited edition status and significant physical weight as well. Of course, the price tag is also pretty high and if you aren't comfortable reading about a $1300 graphics card you might as well turn around now... For those that dare though, you can be sure that the MARS II will have you dreaming about PC gaming power for years to come!
