Ah, RumorTT, it's my favorite part of the day. Recent rumbles are pointing toward NVIDIA launching its GEFORCE GTX 670 alongside their dual-Kepler-based GTX 690 graphics card. This comes from Fudzilla, who notes their sources are talking of a May 10 launch date for both GPUs.
We're just hours away from the official announcement of some sort at the GeForce LAN/NVIDIA Gaming Festival (NGF) in Shanghai, China, on the April 28. This is where we should see NVIDIA's dual GK104 GPU, the GTX 690. Fudzilla's sources are saying that the official release date is the 10th of May, and that the GTX 690 should see a partner in its launch in the form of the GTX 670.
Availability, that's always an important question with GPU launches. GTX 690 availability is said to be not great at all, with some partners receiving cards next week. We should have more information as this happens. More news as it happens.
