Wow, the are pretty expensive retail.
I wish Asus would put 2 or 4 750Ti cores on one card and call it MARS IV or whatever.
I'd buy a dozen. Price doesn't matter

If price doesn't matter then why not just pickup a GeoForce GTX Titan Z?

(Or depending on performance a Tesla K40?)
The TitanZ would give you 5760 CUDA cores vs the 750ti 640 cores.
Downside is that it's 50% more then just buying 2 GeoForce GTX Titans.
I'm half temped to pick one up next month just to have the "hottest" toy available. Of course I'd probably just go for the non "Z" version which is one GPU at half the cores.
