As long as you are using Gentoo 64-bit there is no need for a new |
| 9 |
install. The only difference is the number of cores, and perhaps |
| 10 |
some new FPU options. |

CHOST is the same. No change. |

CFLAGS may need to be altered. Some Intel quads have SSE 4.1 while others |
| 17 |
have SSE 3. You need to check the exact processor version to find out |
| 18 |
which is present. |

Also you can set MAKEOPTS="-j5" for the quad processor. |

If you are compiling your own kernel, you may want to change the |
| 23 |
NR_CPUS configure option to 4, and if the new cpu has hyperthreading |
| 24 |
as well, then also select SCHED_SMT. |
| 25 |
|
| 26 |
I assume that for the previous Core2 duo you already have the multi-core |
| 27 |
scheduler support, SCHED_MC, selected. |

Beyond these small changes, nothing new is required. Just pop the |
| 30 |
new quad in and go. |
