IIRC the old Athlon cores didn't support SSE, they started doing so
when they got the -XP badge slapped on.
An easy way to check this is to boot Linux on the box and do:
$ grep ^flags /proc/cpuinfo
Example output (from a fairly recent P4 box):
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca
cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe pni
monitor ds_cpl cid xtpr
Check for the presence of 'sse', and 'mmx'.
And I hate redundancy, and having different functions for the same thing.
