Which capture card has the lowest latency?

[SkySreamer]

I need capture cards with low latency for Broadcast.
I would pay 1500$.

I heard Elgato 4K Pro has 30ms but is there lower latency cards?

For that budget, you could buy a whole new dedicated desktop computer with several PCIe slots, take 2 of those slots for a GPU, and another 1 for a capture card. That'll beat any USB capture, easily.
