I cannot really recommend what I'm using and I certainly don't |
| 32 |
consider this advice but I'm happy to share it. Note that in general I |
| 33 |
tend to keep use flags limited in make.conf and then add them to |
| 34 |
packages I emerge. |
| 35 |
|
| 36 |
The processor is an Intel i7-980x, ATI 5770 VGA. |

I think this conversation could result in interesting learning. (For |
| 39 |
me anyway!) If there are things that improve performance then we'd all |
| 40 |
like to be better educated. |
