There is no additional slow down for AMD64 / EM64T since it's (simplified) |
| 14 |
just a normal 86 with some extra registers and instructions to handle them.* |

There are some annoyances (for example Google Earth doesn't start at the |
| 17 |
moment) but I don't miss anything else. And concerning flash: There are ways |
| 18 |
to work around it (somewhere in the wiki, look for an AMD64-Howto). |
