Is it worth spending ~$20 more for a 4Gb version versus a 2Gb version for my scenario? (2955U processor)

I'm new to Kodi, and I plan to use a Chromebox as a starting point. I'd like to use it as a PVR with Openelec, tvheadend, and a SiliconDust ATSC tuner, plus a USB drive to store recordings. Ideally recording one show while watching another. I will use 1080P, via HDMI, and the SiliconDust tuner and Chromebox will be connected thru ethernet

I might also want to watch a streaming video (say, Netflix) while the PVR is recording an OTA show

Would 4Gb make any difference? The cost differential is small, but worth doing only if there's a return

As a side question: will a Chromebox have enough power to do it? I have seen even RPi2 configurations doing similar workloads, so I hope that a Chromebox would have enough horsepower...

no issues with power to do what you want. I'd go with 4GB (2x2GB) not for the extra RAM, but for the additional memory bandwidth available when running in dual channel mode

My first post, and I receive an answer from "Mr Chromebox" himself... Paint me impressed

Thanks for the prompt answer, off to ordering everything I need...
