Video card

Probably the worst time of the year right after boxing day deals are over, but I'm thinking of upgrading my video card.

Looking at possibly a Radeon RX 560 4gb or something similar. Currently this card sells for 180$ on Amazon, but reading through the forums, it looks like it went down to about 140$ during boxing day.

If I wanted to get this card or a similar one in the next weeks, what kind of deals are out there?

Thanks!
