I don't usually post all the stuff I impulse-back on Kickstarter, but I thought this one was particularly awesome:

https://www.kickstarter.com/projects/udoo/udoo-x86-the-most-powerful-maker-board-ever

From the site's intro:

 

UDOO X86 is the New PC: the most powerful maker board ever and an Arduino™ 101-compatible platform, all embedded on the same board.

On UDOO X86 you can run all the software available for the PC world, from gaming to video streaming, from graphical editors to professional development platforms, plus all the software for the Arduino™ 101 world, including all the sketches, libraries and the official Arduino™ 101 IDE.

You won't ever worry about lack of drivers or stuff like that. 

This is a true next-generation computer.

...

UDOO X86 is 10 times more powerful than Raspberry Pi 3, able to drive up to three 4K screens at the same time.

It is based on Quad Core 64-bit new-generation x86 processors made by Intel®, designed for the PC domain. Prodigious processors concentrated in 14 nm, with an amount of energy consumption of 5 or 6 Watt.

The UDOO X86 embedds the newest Arduino™ 101, with all the upgrades - including 6-axis accelerometer and gyroscope and Bluetooth Low Energy connectivity.
