Specs wise, both version will feature 480 CUDA cores, 320-bit memory interface paired up with 1280MB of GDDR5 memory, Twin Frozr III cooler and a tweaked custom PCB with a 6+1-phase VRM, Military Class II components, over-voltage support (GPU, memory and VDDCI), and a hardware P/S switch that puts the card in either "performance" or "silent" mode. The reference clocked one works at 732/1464/3800MHz for GPU, shaders and memory while the OC Edition will work at slightly higher 770/1540/4000MHz settings. Of course we are quite sure that these numbers can go much higher considering the PCB and the choice of cooler.
In case you missed it on some of the previously launched cards, the Twin Frozr III cooler features dual-slot design with copper base, five copper heatpipes (two 8mm SuperPipes), a VRM and memory heatsink, and two 80mm PWM fans that feature a new "propeller" blade design. According to MSI, this cooler is enough to keep the card up to 18 degrees Celsius cooler and up to 7.7dBA quieter when compared to reference cards.
The new MSI GTX 570 Twin Frozr III Power Edition has already shown up in Europe for pre-order (OC version) and is currently listed for as low as €312,30 and Austrian/Germany Alternate is listing it at €339. You can find it here.
