FUD Zilla heard a rumor that a mainstream version of NVIDIA's Fermi GPU is scheduled for late Q1 2010. ATI's budget DX11 parts were released yesterday.
In perspective, Fermi will be released as a performance chip card, a high-end single chip card, and a dual-GPU card that might launch a few weeks later.
When it comes to entry level and mainstream segments, we will most likely have to wait until around March, if not even later. Despite the huge flexibility of Nvidia's Fermi GF100 architecture, it still takes time to derive slower performing chips from the original design.
