my main setup is i7-8700 / 32GB ram, dahua cams 4mp @20ps (21 cams at the moment, up to 35 soon). question is should i give up quicksync for aliexpress Xeon?
35 cams at 20ps needs around 31,500 cpu mark score. my i7 is around 12,000 cpu mark. xeon e5-2697A V4 is 21,368 score priced around 38$ on aliexpress. combine 2 units for 42,736 score!
dual socket mobos are also very cheap around 90$. all in all too good to be true.

so i7-8700 with 12,000 cpu score + quicksync vs 42,000 xeon without quicksync?
what would be the best option?
thanks

FWIW, if the PC is for a recent version of Blue Iris VMS, Quicksync in most cases offers less benefits to the CPU than does using camera sub streams, as here:
