Thanks to Melvin for the heads up. I managed to get quite a good deal for the Asus ROG Strix RX VEGA56 OC Edition 8GB (ROG-STRIX-RXVEGA56-O8G-GAMING) on Lazada.
I got it for S$499 which is a massive discount from the usual price of S$1,179. At first, I was wondering whether it is a fake since the discount seems absurd.
