I know you recommended the 9xx series because they run cooler, but the power and temperature difference isn't that large right now because EIST support in the 9xx series is disabled preventing downclocking when idle.
This is true but you have to consider that 830 has 130W TDP while both 920 and 930 have 95W TDP. IMO it is more important that you have lower temperatures under heavy load than when your CPU is idle. My temps are 40°C in idle and 60°C at full load with 930 chip while box cooler is running at 1,000 RPM.
For anyone who is not after top models from Intel (940 and above) non-working EIST/C1E doesn't make any difference so they can safely get this revision. Even those who will go after those faster chips with higher TDP will most probably disable those powersaving features if they are into overclocking. Those who care about powersaving should wait for new revision of 9x0 which is due soon (I believe in March) -- they can find S-Spec numbers of the new core steppings in Intel specification update (a.k.a. errata docs).
Another reason why I wouldn't recommend 8x0 series is that they have half the L2 cache 9x0 has, and they don't have Vanderpool Technology (a.k.a. virtualization).
As far as chipsets go, I wasn't suggesting detailed guide with features, etc. What you need is recommendation -- which chipset goes best with recommended CPUs from both vendors.
Please allow me to point out a couple innacuracies :

The first Pentium 4's ran on Socket 478, which is Dual Channel, DDR1 Memory.
The first P4 was based on the 180nm Willamette core which ran on the short lived Socket 423, PC-100 SDRAM and PC-800 RDRAM were the norm back then.

The Pentium 4 Prescott has larger Level 2 Cache, 2MB vs. 512KB or 1MB in the Athlon 64. Which is in place to leverage the bottlenecked Front Side Bus, but I personally believe that larger Level 2 Cache does not mean greater performance, and in some cases, I believe it to decrease performance.
A larger cache won't decrease performance in itself but the manufacturers do have to trade off latency in order to implement the larger cache while increasing CPU frequencies.
As you can see Here the L2 cache latency went from 16 cycles for the Northwood to 23 cycles and 27 for the Prescott and Prescott 2M respectively.
That post is sticky material, thanks for spending your time on it
Thank you for correcting my P4 first socket, but when I mentioned the Latency issue, that is what I personally have noticed comparing a 3500+, 3700+, 3800+, 4000+ for A64 and 530, 630, 540, and 640 for P4. I cannot comment on what benchmarks show, but my personal use, I have noticed small decreases in performance in some appz using higher cache, but that is just a personal experience.
Piddy: It was locked because the moderators were reviewing it for Sticky, unfortunately, due to me being new and my "not the nicest guy" attitude, they have refused. But in the future, it may be up for sticky again.
Thanks Lumi, I appreciate that alot. I have an update planned, actually within the next few minutes, read the original post for changes , I think you'll find them helpful.
Chipsets probably belong in another thread, sicne they can get very complicated, and we dont want too much in one thread.
hey hergie i wont post any bias cause mike asked so nicely ok and watch out for windshear and ycon.
I couldn't resist responding to this... I'm not biased against AMD, AMD makes very good processors, however, I like my Intel P4 better... because it runs cool, and overclocks well, and outperforms AMD's, IMO. Simply a matter of opinion. I'd be happy to use an AMD or recommend it to someone if they weren't going to overclock at all. Just thought I'd clear that up.
Windshear, I gotta ask: How "cool" is your P4? And how fast do you have it at? I'm just curious because I know my 3700+ OC'd to 2.6GHz would probably beat any P4 4GHz or below in Performance and Heat, mine stays 29c Idle and 36c Load, w/ Stock HSF, throw on my Tornado, and load temps are 33c and 27c idle. Pretty low temps for somethin' that benches above an FX-55 8O.
i don't know why they didn't make this a sticky, if its accurate and informative, your personality shouldn't matter, and your not a noob cause i saw you have an sli website and it looked pretty professional.
I'm not sure where he got that from, the only website I have is my Rubyworks Entertainment, and that server is RAMless right now. He must have saw something else and refrenced it to me, which is fine 'cuz I know enough about SLI I should make my own site ....I probably will..hehe.
I'm glad you asked WINDSHEAR that. I wanted him to compare to my 3200 venice @ 2.5, since I think a 25% OC is not terrible, but didn't want to turn this into a fanboy war thread.
Not that he has a chance of beating our OCs unless he is using liquid.
Where ever did he get the idea that Amds dont OC?
Not sure, there is a fact that AMD's don't overclock as high (a 2GHz Venice will get to about 3GHz +-10% stable, but not much after that) whereas a 3.0Ghz P4 could hit 5GHz (100c idle and 150c load though, and i bet that 3GHz AMD would still beat it).
