Yeah I checked that msi support but as I mentioned if you contact them they ask you where did you buy it and to contact that seller.
They offer warranty only if you buy card directly from them.
AFAIK, MSI do not sell direct.
In a lot of regions, including Europe, the retailer is the first port of call as they liase with the manufacturers - but that does not invalidate the manufacturer's warranty directly, as stores can go out of business etc.
If the card is used, that's one thing. As I would expect local consumer laws to take precedence, but I would fully expect the retailer to be comfortable enough to warrant a product, if new (as required by law/manufacturer handles anyway) or even if lightly used.
Given it's only been 6 months since the 2060 came to market, the fact the retailer won't offer a warranty themselves, nor does it sound like they'd be prepared to liase with MSI on your behalf,..... I'd be inclined to avoid that retailer.
Prices for 1660 Ti are high as well here,around 300-320 euros depending on model.
But I don't think that model is good choice for future gaming at 1080p,so I asked about RTX 2060.
A 1660TI is in the same general ballpark as a 2060, usually within about 10%, but varies depending on the title.
Either a 1660TI or 2060 will last you a
long time at 1080p. Sure, the 1660TI lacks the full RTX ability..... but really, the 2060 isn't a card that should be offered as a "true" raytracing card anyway.
If a 1660TI is the same price(ish) as what I can only assume is a used 2060 with no easily accessible warranty, I'd take the 1660TI all day long.
