Just came across this while surfing, best price I have seen for a 780 Ti.
$200 off! (was $799, get in while stocks last) The Gigabyte GeForce GTX 780 Ti GHz Edition graphics card features the new Windforce 3X 2 slot 450W cooler, a base clock of 1085MHz with a boost clock of 1150MHz, 3072MB 384-bit GDDR5 memory, PCI-E 3.0, DirectX 11.2 support, OpenGL 4.3 support, 2x DVI, HDMI, DisplayPort and more. Backed by a 3 year Gigabyte warranty.
You're better off buying a GTX 980 for the HDMI 2.0 compatibility. It should be able to be imported for a similar price.
