The unboxing begins with Linus describing Gigabyte's Z68X-UD4-B3 motherboard as part of a new line built around Intel's Z68 chipset, highlighting its support for LGA 1155 processors and the PCIe-enabled features that allow onboard Intel graphics to coexist with a discrete GPU, which he identifies as a key differentiator from the P67 lineup. He points out a robust power design, noting 16 phases, solid MOSFET cooling, and the overall premium, matte black PCB aesthetic that Linus often emphasizes as a sign of build quality. Throughout the segment, he calls attention to several Gigabyte technologies such as USB Power 3x, USB 3.0, SATA3, ferrite core chokes, and a large assortment of ports and connectors including two PCIe 16x slots (one wired for 8x when running SLI or CrossFire), plus back panel I/O with esata and USB 3.0, all arranged for a high-performance system. Linus also explains the EFI BIOS integration on this line and the notable inclusion of dual SLI/CrossFire support with a focus on the practical benefits of the Z68’s Smart Response technology, which allows an SSD to cache hard drive data for faster access. The first look shifts into hands-on evaluation of the board’s layout, including the six front-panel connectors, front USB headers, and the distinctive black-on-black aesthetic that aligns with the platform’s premium feel. He closes by framing the Z68X-UD4-B3 as a complete platform that combines traditional expansion with advanced Intel features, setting expectations for balanced performance, expansion flexibility, and future-proofing with caching capabilities that leverage SSD technology.

Questions answered

What chipset feature enables onboard video to work with a discrete GPU on the Z68X-UD4-B3?
The Z68 chipset supports Intel's Smart Response technology and onboard video on the LGA 1155 platform, allowing the integrated graphics to function alongside a PCIe graphics card in configurations like SLI or CrossFire.
What is the Intel Smart Response Technology as described in the unboxing?
Intel Smart Response Technology allows an SSD to be used as a cache for a hard drive, speeding up access to frequently used files and programs by storing them on the fast SSD while maintaining the larger HDD storage.
How many PCIe x16 slots and lanes does the board expose, and what is the practical consequence for multi-GPU setups?
The board provides two PCIe x16 slots, with one wired as 8x when running two dual-slot GPUs in SLI or CrossFire, which means the second slot runs at 8x, offering negligible performance loss for most setups.
