NUMA is specialization, imho: |

The more cores the better. 6 and 8 are readily available. |
| 12 |
The 6 core AMD near 4 GHz is the sweet spot, imho. |

Here is a 4 core on sale at Newegg: AMD FX-4170 Zambezi 4.2GHz |

If you run a feature rich desktop (kde, gnome, etc) then the more cores the |
| 16 |
better. Compiling code is much faster and you can still have a snappy |
| 17 |
desk top. Most gentoo folks compile quite a bit of code, depending on your |
| 18 |
updates and how often you experiment with new features or software. |

I'm setting up some new FX-8350 machines, but fully flushed out, there |
| 21 |
around a 1K (USD). Surely you can replace a mobo with a quad and as much ram as |
| 22 |
will fit, and get a fine machine. CPU speed, for me, is the dominate feature, |
| 23 |
when you are only doing a few things for a snappy workstation. Lots of cores and |
| 24 |
low CPU speed and low ram, sucks, imho. Max amount and max speed of the RAM |
| 25 |
is the killer performance edge for most workstations, imho. |
| 26 |

It boils down to a personal decision. The world of software |
| 28 |
is migrating to multi-threading, so the more cores, the |
| 29 |
more future-proof, imho. |
