    I'm looking at Pentium 4 CPUs and apparently there are these two flavors. Which one do I choose?

    Actually, there's 3 differenct varieties, including the Extreme Edition. Which is best is a question of what applications you plan to use it for and how much you want to spend.

    I'm planning to build a super duper home/photoshop computer based on P4 3.0GHz or so. No games, no overclock.

    Say I go with a P4 3.0 whatever the flavor, what MB do you recommend? My two candidates are:

    Asus P4C800 Deluxe
    or
    Abit IC7-G MaxII (or is it MaxIII now?)

    P4 Northwood only has 512 on die cache memory.

    P4 Prescott has 1 Meg on die cache memory.

    Prescott runs hotter.

    Those are both great motherboards. Try an asus P4C800E-deluxe

    I just got an Abit IC7G (MaxII). Great board.

    Also the Prescott has longer instruction pipelines so it runs a TAD slower than the equivalent Northwood. For example a 3.2GHz Prescott performs roughly the same as a 3.0GHz Northwood, on paper anyways. I have owned both (currently running a 2.8GHz Prescott at 3.4GHz), and in benchmarks my previous 2.6GHz Northwood creams my 2.8GHz Prescott. In reality, I did not notice a difference, UNTIL I overclocked it.

    I second the vote for the Asus board!

    Also, you should know that the temperature difference between the Northwood and Prescott isn't real big; only about 4C to 7C under full load. However, I should point out that my case cost over $100 w/o PSU and has a half-dozen cooling fans installed; your temps, should you set this rig up in a smaller, less-breezy case would obviously be higher. Maybe by a lot...

    If you get the Asus board you can run any of the procs listed here; many older MOBO's have issues with Prescott and Extreme Ed. CPU's due to the extra wattage these chips require. You can see the results of a test of this phenomenon here.

    A lot of old boards will not boot at all with a Scotty or EE in place!

    I chose the 2.8E and have not regretted it; I do a lot of gaming along with other intensive apps like video editing.

    If you want to spend over $500, get an Extreme. Otherwise, a C class (NW) will serve you just as well as a Prescott.

    Good luck,

    Or better.

    Clock for clock Northwood outperforms Prescott at the same speed under 3.6 GHz. After that Prescott starts winning the battles because it scales much better.
