I have an Asus P4C800E-Deluxe with a 3.0Ghz Northwood P4. The mobo is socket 478 and the only upgrade path without replacing the motherboard is to the P4 Extreme Edition. I've been looking regularly at prices and I haven't seen the P4 3.2Ghz S478 Extreme Edition CPU budge much. In fact looking at Scan's prices today....
S478
3.2GHz EXTREME Intel Pentium® 4 S478 CPU "Gallatin" (800FSB) 2M Cache *Retail* £339.00 £398.33
S775
670 Intel Pentium® 4 LGA 775 CPU (3.80 Ghz 800FSB) HT 2MB Cache with Intel® EM64T *Retail* £342.25 £402.14
Why is the S478 P4EE CPU still so expensive???? I know that it has 2Mb Cache but then so does the S755 P4 670!!! I'd be better off replacing the motherboard and going for a S775 CPU wouldn't I???? Do you think if I hold out I will be able to pick up a S478 3.2Ghz EE CPU for a reasonable price or will it always be unfeasibly expensive?????
