An interesting feature is the presence of a heatsink on both the chipset and the power supply, potentially allowing for some overclocking to be done. Especially the 22nm Ivy Bridge chips are suited for this, given the relatively low TDP of 77 watts for the quad-core models. The model with the H77 chipset only offers limited overclocking options (up to four speedbins beyond the maximum Turbo boost), while the Z77 board supports multipliers of up to 57x, at least in theory. In terms of video outputs, the Z77 comes with 2x HDMI and 1x mini-DisplayPort, while the H77 is equipped with DVI, HDMI and DisplayPort. Furthermore, the Z77 features four SATA connectors (2x 6 Gbps and 2x 3 Gbps) and the H77 even has six such connectors (2x 6 Gbps, 3x3 Gbps internal and 1x eSATA 3 Gbps).
Having first seen the mainboards during Zotac's CES showcase in January, they should now become available shortly. It is not clear at the moment what the price for the boards will be.
