NVIDIA's next-gen 65nm G94 card is due for release just one week from now (Feb 21); this being the GeForce 9600 GT which is aimed at the mid-range market segment to compete with ATI's Radeon HD 3800 series.
In typical form the card sports a 256-bit memory interface with support for 64 shader processors and 512MB of GDDR3 memory, however early signs from MSI let us know there'll be quite a few varying models across the board as they plan to release not one, not two, but FOUR versions differing in the way of clockspeeds / amount of memory.
The first three cards mentioned above will have identical clocks - 650, 1625 and 1800 MHz for the GPU, 64 Stream Processors and GDDR3 memory respectively while the OC edition will be set to 700/1750/1900 MHz. Also, for the 1GB and the OC models MSI is set on using some custom cooling which comes in the form of a dual-slot solution with a nice big fan, two heatpipes and a transparent casing that will cover the whole of the PCB. The downside of the two cards will probably be price which is likely to be over $200. The ETA for the first cards is February 21st.
