Mainboard manufacturers also can throw in nonsense like ULTRA DURABLE and TUFF NOW WiTH 2oz of copper!! Gigglibyte has ULTRA DURABLE 2, 3, 4, maybe 5 to make SURE that everyone understands that their mainboards are ULTRA DURABLE!!!! and then at least a few of them have MILITARY GRADE CAPACITORS!! and MILITARY GRADE chokes!!
And of course the whole JAPANESE CAPACITORS ONLY!!! to give the feeling that it would make your mainbioard ULTRA DURABLE MILITARY GRADE TUFF!!
Oh and yes with RGB it will run cooler and faster!!
As for capacitors, so yeah, Rubycon etc make excellent capacitors but the capacitor plague is at least 20 years ago and Taiwanese and Chinese manufacturers aren't sitting still and the latter is very much trrying to be independent from others so nowadays having Chinese or Taiwanese caps isn't as much as a disadvantage anymore, also Japanese manufacturers had batches of real unreliable stinkers as well...
