The AW3423DW is 175Hz and has a G-Sync Ultimate chip. Not to be confused with the AW3423DWF (which is freesync and 165Hz)
Not an all time low, but still a mark down in price. Not as good value as the Samsung G9 49" OLED for $1770, but not everyone wants a super ultrawide.
Last time it was this price I matched with JB and used the TCN 15% off GC it's a fantastic monitor and I've never hear the fan once
