Any idea???

What type of monitor do you use? I happen to have a very similar system to yours, and originally had the same symptoms you described. My primary issue involved the fact that I don't use a traditional computer monitor; I use an HDTV... If you happen to use an actual TV like it was a monitor, there are settings in the ATi Catalyst software where you need to tell your video card that you are using an HDTV, set the card to the correct native resolution and framerate (A 1920x1080 capable computer monitor and a 1080p60Hz HDTV are VERY different from your graphics card's point of view).

Second, I ended up noticing a VERY different level of performance when swapping between Skyrim's Windowed mode and Full screen mode. For my machine (which is more powerful than yours, but not by very much), windowed mode eliminated all trace of my poor framerate and CTD problems. Naturally, a game of Skyrim's beauty deserves fullscreen play. Try Windowed mode for a while as a troubleshooting step. If Skyrim responds better in Windoed, then I would recommend the addon called SBW, or Simple Borderless Window. You set Skyrim to run in your native resolution in windowed mode, and then replace the Skyrim executable with the SBW executable. You laungh the game using the SBW.exe. The game begins by loading in windowed mode, and then SBW does something to either delete the window frame, or zoom your screen, and makes Skyrim look like it is fullscreen. The image still looks just as good as a true 1080P HD image, and in my case, if there is a loss in resolution, it is negligible, and the vast improvement in framerate and playability of the game more than makes up for it...
