Inno3D is one of the rare partners that decided to launch a custom GTX 780, the Inno3D GTX 780 HerculeZ 2000.
While the reference based GTX 780 graphics cards are stuck at 863MHz base and 900MHz Boost GPU clocks, the Inno3D GTX 780 HerculeZ 2000 works with a decent 900MHz base and 936MHz Boost factory-overclock. It still features the same 3GB of GDDR5 memory clocked at reference 6Ghz and paired up with a 384-bit memory interface.
Inno3D also launched a reference GTX 780 as well but that one is stuck with a reference blower-style GTX Titan cooler and reference clock speeds.
Both Inno3D GTX 780 graphics cards should be already available in retail/e-tail.
