Possible processor upgrade...questions.

Right now, the box I use for everything has all that you see in my sig. installed. I'm running an Athlon 1.33 GHz, and with the drop in prices I'm thinking about getting an Athlon XP. The trouble is, everything is optimized:

CFLAGS='-march=athlon -mcpu=athlon -O3 -pipe'
CXXFLAGS='-march=athlon -mcpu=athlon -O3 -pipe'

So I was thinking of compiling a few Athlon XP kernel bzImages to keep around for upgrade time. What I DON'T want to do is to have to re-install anything, especially like X or Openoffice in Gentoo. Can anybody offer any insight?

do you feel the gentoo is more good? In my mind, to build a system is just to kill time.:D

Well, the difference between Athlon and Athlon XP optimizations are very small, since the only difference other than speed and size between the 2 is that XP suports Intel's SSE instructions.
That said, you should be able to do it just fine without breaking anything. When you make menuconfig, just copy over your current kernels config, and do a make oldconfig first. That way you have all the same support options in your new kernel.

So you think if I set it up to boot from an "XP" kernel, switch CPU's and restart, all the apps will work, too? If so, I think I'll just change CPU's, reboot and then build a new kernel, if I can.
