Because it costs $400 right now. And I'd rather get an RTX 3070 at that price.That's bonkers. That's barely cheaper than a 2060.
$350:
Amazon.com: Gigabyte GV-N105TD5-4GD GeForce GTX 1050 Ti D5 4GB GDDR5 Graphics Card: Computers & Accessories
Actually newegg has a few for $300:
GIGABYTE GeForce GTX 1050 Ti DirectX 12 GV-N105TD5-4GD Video Cards - Newegg.com
Still, I don't want to spend a huge amount of money on a medium tier card.
