Club 3D has officially released its overclocked HD 5800 series cards, the HD 5850 and HD 5870 Overclocked Edition.

Both cards feature a custom dual-slot cooler with four heatpipes and a larger and thus quieter 90mm fan. The new cooling should provide up to 10 percent lower temperatures and it will feature a much lower noise level compared to reference coolers.

The HD 5850 Overclocked Edition has 1440 stream processors, works at 760MHz for the GPU and comes with 1GB of GDDR5 memory clocked at 4200MHz. The HD 5870 Overclocked Edition has 1600 stream processors, 875MHz GPU clock and 1GB of GDDR5 memory clocked at a quite impressive 4900MHz.

Both cards feature a 256-bit memory interface, support for DirectX 11, ATI's CrossfireX and Eyefinity and come with two DVI, HDMI and Display Port outputs.

The Club 3D HD 5870 Overclocked Edition is already listed with a lowest price set at €375, while the HD 5850 Overclocked Edition should show up in retail/e-tail pretty soon.
