If you are talking about warranties, look at EVGA.
They offer a lifetime warranty to the original purchaser if you register the card within 90 days.
Past that, the warranty is transferrable to a second user.
Here are the details:

Your two choices differ more than the graphics card.
I think I would give up I5-8500 for the i5-8400 to get a 2 x 8gb ram kit.
I think also that I would prefer hitachi HDD vs. Seagate for reliability.
FWIW
I will never again build without a ssd for the "C" drive. It makes everything you do much quicker.
120gb is minimum, it will hold the os and a handful of games.
But, many things default to the "C" drive.
When a SSD nears full, it will lose performance and endurance.
240gb is the recommended minimum.
If you can go 240gb, or 500gb you may never need a hard drive.
You can defer on the hard drive unless you need to store large files such as video's.
It is easy to add a hard drive later.
Samsung EVO is a good choice for performance and reliability.
