The MSi R5770-PM2D1G-OC is a desktop graphics card based on the mid-range ATI Radeon HD 5770. It supports DirectX 11 and utilizes 1 GB of GDDR5 memory, with a core clock speed of 850 MHz, like the HD 5770. It differs from the R5770-PM2D1G only in adding VGA connectivity via included DVI-to-D-Sub adapters. It lacks the more advanced cooling and overclocking capabilities of the PMD1G. Overclocking is still possible, however, via Afterburner and MSi Dot Express technology. It also includes features not available with MSi's lower-end graphics cards, including ATI CrossFireX for multi-GPU scalability, and ATI Stream, which accelerates certain non-graphical applications. The graphics card supports DisplayPort and HDMI outputs in addition to DVI and VGA.
