Wrong forum? Anyways, from what I understand, the 1.26 GHz PIII is to be the fastest PIII based on the Tualatin core. Intel is to phase out the PIIIs in order to focus on the P4s. The new Celerons, however, will be based off the Tualatin core (the 1.2GHz celery is a tualatin). The PIII 1.26 GHz may be the fastest tualtin based CPU your mobo can support, unless Intel bumps up the fsb of the Celeron from 100 MHz to 133 Mhz. And a 1.53 GHz Celeron with a 133 MHz fsb might just be faster than a PIII 1.26 GHz. The Celerons with a 100 MHz fsb should, however, make for a good overclocking CPU. (the Celeron 1.2 GHz @ 100 MHz fsb could be 1.6 GHz @ 133 MHz fsb)
