P4 chip with 1mb cache compatible with Motherboard?

my motherboard is qdi superb 4le http://www.qdigrp.com/qdisite/eng/products/S4le.htm
and i want to know if a cpu with 1mb L2 cache will be compatible , actually this cpu http://processorfinder.intel.com/details.aspx?sSpec=SL7E2#
the one i have now is a celeron 2.4 with 128 l2 cache so i think its this one http://processorfinder.intel.com/details.aspx?sSpec=SL6W4 since cpuid also matches.

thanks Oscar

the ones with ht are pretty expensive so i ll go with the cheap solution (that cpu costs ~20 euros) ,i ve checked that the socket and fsb are the ones needed but my concern is the L2 cache and if that might cause incompatibility, but does cpu cache have anything to do with the mobo? as i see it its only in the cpu part and doesnt have anything to do with the mobo, but i dont know much
do you really thing that there isnt gonna be any noticable change in my computer if i change the cpu? (i am asking, i dont know :-/ ) doesnt it worth the change?
i mean i move from celeron->p4 , 2.4->2.8 , 128kb cache->1mb (dont know if the last makes any difference )
thanks for helping
