Thanks, ya I know they are old - but I'd also add that CPU performance has far outpaced application need in the office. No sence in replacing P4 chips.
the motherboard has to be p4 compatible in order to operate..... just because it is LGA 775 does not mean it will support all 775's..... the same thing happend to me back when I tried to upgrade from a pent D to a C2D....
