Chinese company Yeston thinks there's still room for factory-overclocked Radeon HD 6870 graphics cards in the market, it unveiled the R6870 Game Master, designed to have high overclocking headroom. The card uses a custom-design PCB with an 8+1+1 phase VRM to power the GPU. The VRM takes advantage of LFPAK MOSFETs and two NEC TOKIN Proadlizers, which condition power and enhance stability with voltage-assisted overclocking. Out of the box, the card ships with reference clock-speeds of 900 MHz core and 1050 MHz (4.20 GHz effective) memory, leaving it entirely to you to take the clock speeds where you want them to go, instead of being spoon-fed with factory-OC profiles.

Moving on to the cooling, Yeston gave the R6870 Game Master a zesty cooling assembly that spans three expansion slots. It uses a lateral-flow design with a blower pushing air through numerous aluminum channels where heat is dissipated to it. It appears like heat is conveyed to these channels using heat-pipes, and not a hot plate. As a nice cosmetic touch, Yeston gave the card a thick back-plate that is ridged. It helps reduce PCB bending and could assist heat dissipation just a little. Display outputs include two each of DVI and mini-DisplayPort, and one HDMI. Power is drawn from two 6-pin PCIe power connectors. Out now in the Chinese market, the Yeston R6870 Game Master is priced at 1,199 RMB (US $190).
