Nvidia is continuing to tease all its fans on Twitter by releasing interesting pictures of its new and much anticipated GF100 Fermi-based video cards. Not a log ago there was a picture of a single GF100 card running an Unigine game engine benchmark and now we have a new picture showing two GF100 cards running in SLI mode. On the image above you can see Tom Petersen, Director of Technical Marketing at NVIDIA (an Apple fan obviously), proudly showing off his new Maingear Shift PC, equipped with two GF100 cards. So when will all this waiting end and we are going to see the new GeForce video cards on the market and be able to buy them… it is still a mystery.
