difference between 130 mbit ( tested ) and 430 mbit ( tested ) is bigger than i thought it would be.
i'm still on the same 300 mbit nominal cable plan but now instead of wifi in my older motherboard i'm using a new wifi adapter, which tripled the speed i am seeing.
combined with the extra ram i put in ( from 16 GB to 32 gb ) it feels like a new computer when browsing.
i do have an actually new computer in another room but it actually feels slower than this one due to a bug in intel VROC causing slow 4K 1QD SSD performance ...
