The HIS Radeon HD 5770 H577FK1GD is a lower middle class PCI Express x16 desktop graphics card featuring the Park(Pro) architecture and manufactured in 40nm. Essentially an upgrade from the HD 5450 H545H1GD1, the HD 5770 H577FK1GD upgrades from 1GB of 650MHz DDR3 to 1GB of 850MHz GDDR5. Plus it offers an improved 128-bit memory interface. This means the card can better handle demanding 3D games, though users are still recommended to use no higher than low-medium settings. Note that the H577FK1GD graphics card relies on HDMI, DVI, and DisplayPort connectivity ports. Note also that the HDMI v1.3 interface is 8-channel HD audio and 1080p video compatible. Due to the additional components, the card also has a dual-slot fan to deal with the additional heat.
