I've seen the V1 for $549 + delivery at Shopping Express so I'm assuming this is a good deal.
The drawback is that it has only one DisplayPort, one HDMI and one DVI-D.
I'd probably recommend a 5700 XT for around this price though if you have no use for CUDA, RTX or NVENC.
Bonus: Comes with Rainbow Six Siege Gold Edition. You can claim it here.
What's the difference between v1 and v2?
I was lucky to get the one from the PcByte Amazon deal a few weeks ago, pretty sure it's v2.
Any major difference?
