It's MSI's slightly-overclocked 4GB RX 480
for RX 470 prices. Kinda hard to beat for a sub-$200 card, and that extra $25 rebate makes it even cheaper. Deal expires at midnight PST.
There's also a PowerColor model
that starts at $190 and ends up at $170 after MIR. This isn't as good of a deal but still gets an honorable mention.
