correct.
also, if that's USA pricing those numbers don't look right to me.
The cheapest GTX1050Ti seems to be $150, but again it doesn't support SLI anyway.
In fact, I think the lowest card to support SLI (more specifically SLI AFR as in Alternate Frame Rendering) is the GTX1070.
Cards are too expensive right now. Nobody knows when the crypto-crash will come but it will and prices will then plummet. We may see GTX1060's down to $250 in just two months or so. Nobody knows.
We may see GTX1080's as low as $500USD in the near future too so you may end up kicking yourself. It's tough to wait I know.
