No , you need a card with at least 2 display ports for that resolution , because DVI and HDMI can't output that high resolution

Is it the regular card or the strix gaming card ?

The strix gaming card has 3 display ports and support your monitors , but the regular card only has 1 display port and can't output to 2 LG ultrawide monitors

Just get any R9 390 that has at least 2 Display port
