Do I have to change my march when switching to an opteron?

I'm expecting my new Opteron 175 to get here tomorrow, and I currently have a Athlon64 3200 Venice, I was looking around so I know what to expect and get my system all prepared. I saw that there is a separate Opteron march, is there any benefit of switching the march?

you will want sse3 support, but remember it's fpu so it probably isn't worth remerging sytem for it.

try adding sse3 to your use flags too, and the do "emerge --newuse --pretend" to see whether anyhing important uses that use flag and might benefit from it being enabled. If it uses the sse3 use flag, it's a good bet it's a good choice in package to remerge if you want to take advantage of things.

opterons are awesome ; ) i hope yours has a meg of cache, becasue if it does, you're gonna be happy.

Even without SSE3 use flag enabled, I still have ~400 packages, I've been putting off a world update until I get my new processor. So I'll add that flag and update when I get it. I did get one of the 1mb l2 cache ones too. Anyway, thanks for all the help
