This graphics card should be launched in mid-February and will be about $25 cheaper than the current GeForce 8800 GTS which has 640MB memory.
The 320MB card is one of the many G80 derivatives expected for Q1'07. NVIDIA CEO Jen-Hsun Huang confirmed the company's plans for more DirectX 10 video cards in an interview late last year.
GeForce 8800 GTS, also known as G80-100, already exists as a 640MB product. All aspects of the 640MB card will remain the same for the 320MB derivative: 500MHz core frequency, 800MHz memory frequency and 96 stream processors. The PCB layout and cooling will remain the same.
Other cards like the GeForce 8400 and GeForce 8600 will be launched before the R600. AMD is expected to launch the ATI R600 at CeBIT in March.
