Soon, I'll be able to upgrade to a 2.6 or 2.8 P4C. For now, I have a 1.7 Celeron (Willamette) on my Asus P4P800 Deluxe. I'm ashamed for pairing my POS Celeron with my Sapphire 9600Pro but, it only happened because I had the Celeron and I wasn't able to upgrade my CPU. Anyways, I have heard that my 1.7 Celeron is about as good as a 1GHz P3 and to try and get everything I can out of it, I must overclock it. I've tried just boosting the FSB (it's at 120 right now, giving 2040 Mhz) but I feel as though i should be tweaking the voltage as well. I would like to be able to hit at least 2.2 GHz. Any suggestions?
