the GTX 460 NDA is over, MSI has rolled out a total of four graphics based on the GTX 460 GPU. All of the cards feature MSI's Cyclone dual-slot cooler and use military class components. In addition to two reference clocked cards, MSI has also rolled out two identical ones but with a slight factory overclock.
The new MSI GTX 460 Cyclone card will be available in 768MB/192-bit or 1GB/256-bit version and while reference ones are clocked at 675MHz for the GPU, 1350MHz for those 336 CUDA cores, the OC series works at 725MHz and 1450MHz. All four version have a 3600MHz clocked GDDR5 memory.
The Cyclone cooler features two heapipes and a 90mm fan and according to MSI should be up to 15.7 percent quiter than the reference card. The cards should also be a bit cooler but bear in mind that this one keeps the hot air mostly inside the case as it has no plastic shroud, rather than to push it out of the case.
The cards should start to appear in retail/e-tail pretty soon.
