Looking for cheap FP64 performance, still Titian Black?

[PiManASM]

I have an application that relies heavily of FP64 performance and large matrix operations, so we're looking to offload some of this work to the GPU. We don't need ECC or constant computing, so the Tesla series seems unnecessary. I was looking into the Titian black, which seems to beat the most of the Tesla lineup in FP64, and it's a whole lot cheaper. Are there any gotchas or things that I'm overlooking with this card? It seems like it'd suit our purpose well.

if you want cheap card with massive FP64 performance yes titan black is still the best option. the only catch is the card have no professional support from nvidia like true tesla card.
