Glad to see everyone is starting to receive their 27" iMacs. I guess I'm shocked that there still is just about zero benchmarks on the 680MX and it's available to the public. (See notebookcheck) So far the 680MX is the best mobile graphics chip on the market, and exclusive to Apple. Now that the 27" iMac is available to the public, please feel free to share any benchmarks you can (not Geekbench). 3DMark would be great! No one knows what to expect of this card yet and I think a lot of us are interested to see what it's capable of! Thanks!
