The early listing at Newegg.com also revealed the factory overclocked EVGA SuperClocked GTX 580 card, which is currently available and selling for US $579.99, US$20 more than the reference clocked one.

The EVGA GTX 580 box shot also reveals that EVGA will probably be working on SSC and FTW versions of the GTX 580 and these usually end up with a higher factory overclock. The EVGA SuperClocked GTX 580 on the other hand works at 797MHz for the GPU, 1594MHz for those 512 CUDA Cores while the memory ended up clocked at 4050MHz. The card still uses, what appears to be, the reference cooler and features two DVI outs and one mini-HDMI out.
