new athlon xp 2

I have an msi k7t turbo2 (MS-6330).

msi site says fastest supported is the thouroughbred's
so the barton 2500 is out, provided no bios updates in future.

its about to be recomissioned to music box or router/server anyway.
It has not:
8x agp
ata133(only ata100)
faster cpu core support, like barton

and I really dont want to replace the mobo at this point because i dont see the point really.

my hope is to add:
300gig maxtor hdd
a new proc (2200 range)
fx5200(just to get the dvi for my lcd.)
and maybe size up one of my ram sticks(128 to 256 for 768 total)
and an xitel hi-fi link

I am runing a duron 1.3ghz, and trying t get out of the duron line(first proc was a 750).
I just wanted something thats got the cache of the athlon xp.
and once you get the same size cach clock speed becomes less important anyway, thats why i said 2200 in the last thread.

the good news is im getting at least 30 for the duron!!!!!!!!!!

and could i possibly wait a month or so for the nvidia 6800's to come in before i buy my 5200 video card?
