intel Pentium 4 630 Prescott 800MHz FSB 2MB L2 Cache LGA 775 EM64T Processor - Retail

Before I speak, I have made a final decision to purchase intel, so please do not recommend that I go with AMD.

So I am wondering what mobo to get with this processor?

Here are a few ones that I found:

1) ASUS P5WD2 Premium Socket T (LGA 775) Intel 955X ATX Intel Motherboard - Retail

2) ASUS P5LD2 Socket T (LGA 775) Intel 945P ATX Intel Motherboard - Retail

3) ASUS P5LD2 Deluxe Socket T (LGA 775) Intel 945P ATX Intel Motherboard - Retail

Questions that I have:

1) If it says DDR 2 800 as the DDR2 standard, does that mean I can use DDR 2 533 1 GB ram, but can upgrade up to DDR 2 800?

2) Do I really need a firewire device on my mobo?

3) Are there other motherboards that I should look after?
