ok, I've decided that I'm going to get a Cedar Mills Celeron D (the 65nm ones) Upgrading is not going to be an issue; my sig rig is going to stay my main computer for a while, and when I upgrade who knows what I'll be doing. The main thing I want is something that can hit 500 fsb and is fairly cheap. I'd rather not spend a whole lot of money on this. If possible, I'd like to keep the price of the CPU + mobo around $100, and the CPU is going to cost around $30-$45. I'll spend more if necessary, but not if there are cheaper options that will do what I need.
I know that some socket 775 motherboards have DDR slots, can I run old ddr memory with this processor (after I overclocked it I'd obviously need to use an insanely small divider xD) or do I have to buy some DDR2?
How is this DFI? it says p4 prescott, can it run 65nm CPUs?
