The 970 EVO Plus is at quite a good price in comparison to other NVMe drives checking Staticice, but because of the massive price difference I'd just opt for a 2TB MX500 for a lot less. The 2060 has my attention though, as it's pretty much at U.S. prices rather than being around $100 more expensive than the 5600 XT.
