Here are key points about the GIGABYTE X99P-SLI.
Intel Thunderbolt 3.0/USB 3.1: The X99P-SLI is the first X99 motherboard with Intel's Thunderbolt 3 certification. The "Alpine Ridge" controller also provides USB 3.1 through the Type-C connector and Type-A connector on the IO panel. I have always looked at Thunderbolt 3 as a high-performance interface best paired with Intel's high-end platform (X99) as opposed to the mainstream (Z170) platform.
Socket with Extra Pins: GIGABYTE's X99P-SLI is towards the bottom of GIGABYTE's X99 lineup, but it carries the socket with extra pins and a switch to enable or disable them. Some people are afraid of the extra pins, and the ability to disable them is a pro for many.
Ultra-Fast M.2: The X99P-SLI carries a 32Gb/s M.2 slot. A lot of people are brand loyal, and those who are loyal to GIGABYTE will be excited to know the X99P-SLI's M.2 slot got an upgrade.
Strong VRM: Although some people might doubt six phases on an X99 motherboard, the X99P-SLI's VRM is quite formidable. It is all about component quality on X99; quantity doesn't provide much since the space for the VRM is so limited on X99. GIGABYTE has provided very high-quality components, even on this mid-range X99 motherboard.
Ready for Next-Gen: A lot of people will be looking to upgrade to the next generation of CPUs for the X99 platform, and the X99P-SLI is fully capable of supporting them with BIOS F20 and beyond.
No POST Code: I think any motherboard that costs north of $200 should come with a POST code display for the sake of debugging. It is not a requirement; I just feel more at ease with the codes since it saves a lot of time if you run into hardware issues.
Intel's X99 chipset is high-end, by definition, any motherboard carrying the X99 chipset is considered high-end. However, until now, Z170 motherboards had more high-end features such as Thunderbolt 3 and dual M.2 slots. The X99P-SLI is based upon the X99-SLI, but for $40 more, you get Thunderbolt 3, USB 3.1, and a 32Gb/s M.2 slot which is a pretty good value considering the cost of the Intel Alpine Ridge chip. The X99-SLI was an excellent value motherboard, and the X99P-SLI is an excellent replacement, especially with the high-end features.
GIGABYTE did not cut any corners to offset the cost of adding in the Thunderbolt 3 controller. Voltage regulator quality is still high, and tiny improvements were made such as swapping in RGB LEDs and adding PCI-E shielding. I was very impressed with the value that this motherboard provided regarding features compared to cost.
For an extra $40 over the X99-SLI, you get a lot of value. If you are looking for a motherboard with the latest in connectivity at an affordable price, the X99P-SLI is an excellent option.
