I'm kind of forced into building my new system now as my current mobo died. I'm getting a Q9450 when I can but in the meantime I plan to run my current CPU which is a Pentium 4 630 3Ghz CPU from 90nm days (Prescott). I just want to make sure this chip will run ok on a P35 chipset. If not I may have to buy a cheap allendale in the meantime...
