ASUS has published over a dozen images of their upcoming Republic of Gamers MATRIX R9 290X and MATRIX GTX 780 Ti graphics cards. Both of these cards make use of a custom PCB and custom cooler.
The dual slot cooler is made up of two fans (one is a CoolTech fan) and a black nickel-plated heatsink that features five direct contact copper heatpipes. These models also have dual 8pin power connectors, a 14 phase DIGI+ VRM, metal backplate, dual-DVI, HDMI and DisplayPort outputs and an LN2 mode switch.
No word yet on actual clocks, pricing or availability yet.
