Youtube's been giving me fits the last couple weeks. Last night it was running at 144p!I have been recommending 32GB of RAM for gaming for a few years now because memory is just so cheap and 16GB just doesn't really cut it anymore. I also highly recommend sticking to 2x 16GB modules because having 4 modules can cause you all sorts of issues with trying to get the RAM running at it's rated speeds and timings.
Also, I have noticed that if I run YouTube videos in the background while I am playing games then the quality automatically gets degraded down to 720p or lower. This is annoying when I go to actually watch a video instead of just listening to it and it is a blurry mess because YT defaults to the last video quality setting it was on lol
Yup! DDR4 is down to only $1.50 a GB (It's literally dropped by about 33% since I looked a few months ago, not that I need more than 32GB but my current box can take 128GB if I need it).
If you are sweating the assets and still have DDR3? Lucky you! I maxed out my Ivy Bridge system a few years ago for like $80, now 16GB DDR3 is $16! It's tempting to spend 0 on an old system but that's not much to spend to get the nice speedup you'd get from a 8GB or (god forbid) 4GB system.
