MU-MIMO may improve or make worse your WiFi speeds depending on your router and devices. SNB - MU-MIMO.

750Mbps is using Broadcom NitroQAM. Your devices have to have a Broadcom chip with NitroQAM and 3 streams to get this speed else your max speed will likely be 300Mbps on 2.4GHz with typical 2 stream devices.

Take note that typically your Wi-Fi actual throughput will be about half the link speed shown on your devices due to overhead and other factors.

No

Intel Wireless AC 7260 has a max link rate of 867 Mbps. Therefore, the max typical actual throughput that can be expected is 4xx Mbps. Still not enough to get the full speed of Unifi 800Mbps. This applies to most laptops and smartphones made in the past 2 years that has 2x2 streams and link-speed of 867 Mbps. Achieving 800 Mbps on Wi-Fi will not be possible even if a very high-end router is being used unless an add-on high-end Wi-Fi adapter is also used on the laptop/PC with link speed exceeding 1 Gbps by some margin.
