I'm running on a pretty dated Dell XPS 1530m (3 years old):
Intel Core 2 Duo 2.0GHz
nVidia GeForce 8600m GT 512MB
Win 7 64-bit OS
I certainly wasn't expecting much at all, but as it met the Minimum Requirements I was hoping I'd at least be able to achieve something playable. Unfortunately even with everything set at Low/Off and on low resolutions the game constantly stutters and remains between 2-15 FPS - moving the settings up or down doesn't seem to affect it at all, for better or worse (only when I crank everything up to the max does it deteriorate further). When trying to access menus or bags it stutters for a second before popping up, movement is choppy and everything just seems that slight bit unresponsive. I daren't step into a Flashpoint as even in Heroics the FPS drops to 2-5, and PvP is just completely unplayable.
I'd happily settle for woeful graphics if it simply ran smooth enough to interact properly with the world...
Here is my DxDiag:
