The kind of people who OC their computers tend to buy the latest tech.
The P4 is now a few generations behind current, so most people here wont have one and probably wont remember what numbers they were getting.

P4's have reached massive numbers in OC records (7Ghz if i remember). However, that was on LN2 type setups. The P4 runs quite hot standard, and unlike C2D and D's to a lesser extent, they were never known for producing big numbers without massive heat issues.

As usual, it always depends on your individual chip, cooling setup, mobo, ram etc, but id say 4Ghz is attainable with some work.

Id save the money on the HSF and put it in the bank towards a C2D system one day.

well i wouldn't say for a C2D system, maybe i3 or PII X2 (LGA775 is EOL socket, no point in buying one new)

If you got the money on hand get a new board (used if you want) and new ram for better results since the 915 is a crapset even for a p4. The p4 can get ok results but only on a modern board for better IPC and a upgrade path for 64bit os support.

well i live melborne aus so everything is slight more expensive than in the states (about $140-$170 for a 4850) so a 4670 is at least $120+
umm 533ram is impossible to find. and the hsf is a funny story (trash and teasure market picked up it for $5 thinking nice looking cheap cooler what a great buy check it online one the best OOH snap.
umm upgrading probally upgraded one part at a time so thinking psu then mb + ram, gpu, cpu. any ways i want stable a overclock for the time being as a first time learning experience. and what do u guys as a tester to see if it works? thanks
