The only problem with the 9xx series, is that you need a more expensive motherboard to get a good OC. The 945 chipset boards get stuck at 225mhz FSB unless you overclock the PCIe bus, and the NF4 chipset boards seem to be getting stuck around 230mhz FSB. It doesn't happen with the single cores on those boards, just with dual cores. Need a 955x or 975x to get a good OC with the 9xx series.
I just did a search on the Abit site and found a substantial list of boards that will support D9xxs
http://www.abit-usa.com/products/mb/intel-pd-9xx.php

Edited: I wasn't sure how to do a search for this info across all the manufacture's sites so I just did a brute force type of search that originated with the Newegg site.

It's not that other boards don't support them, it's that they get stuck at 225mhz FSB, drasticly limiting the overclock.
I see, so in order to get the D940 (with mult x16) to 4xxx, it has to do 250 FSB. I thought the multiplier was not locked in the D9xx???, just in the D8xx (& others) for example??

Multi is locked on the 9xx series as well.

I am not questioning your temps etc.; however, why compare an AMD 3800 to the Intel 805. Doesn't the 3800 cost about twice as much? It looks like the AMD Sempron 3600+ and the Athlon 64 3200+ are comparatively priced with the Intel D 805.
Am I missing something?

The 805 requires a good motherboard.. expensive... you can't just get your typical no-frill socket 775 motherboard and expect to overclock the $hit out of the 805...on the otherhand, the X2 3800 will run and overclock on pretty much anything, including the kitchen sink.. in addition, you can use the stock cooler and achieve a decent overclock.
The Intel 805, on the other hand, requires an aftermarket heatsink, to achieve some sort of better cooling that the stock cooler doesn't provide.

The Intel 805 is most likely dependent on the Intel System builder's guide, Compatible 4A/5A code (I think thats the code), which means you need at least 16A on one of the 12v rails..and that is a minimum..
So, you're going to need a good power supply, with alot of overhead..

We aren't talking about stock speeds, we are talking about overclocking. You need a more expensive motherboard, power supply and cooling to overclock the 805, making the cost of a 3800+ X2 system almost the same. In that situation, the overclocking of the 3800+ is superior to that of the 805. Even at 4.1ghz the 805 was losing to a stock 4600+ which runs at 2.4ghz. The 3800+ usualy reaches a minimum of 2.5ghz, and the newere revisions are hitting 2.8ghz commonly. I tried my damndest, with 4 pentium-d's and 5 differant motherboards to get a pentium-d to match the performance of my X2 @2.618ghz, and none of them could do it.

OK, so you are saying that neither the Pentium D 805 or the Athlon 64 3800+ with motherboard will work for under $200.

So if a stock D 805 does not outperform a Sempron 3600+ and the Athlon 64 3200+, then whcih one of those two AMD's would be better for Photoshop and DVD copying?

I have seen specs for WinRAR and Doom games etc. but that is not my load.

Of course if Intel drops the D930 down about a $100 this week, then its a new ballgame.

Thanks.

I was refering to a 3800+ X2 dual core, saying it will overclock nicely on a less expensive motherboard without expensive cooling. At stock speeds the 805 will still beat the single cores in that price range for what you are doing.

If I do go with an AMD CPU (due to heat & power consumption issues), which one would be the best performance for the money including overclocking. Remember, I need to get the CPU and motherboard under $200. Looks like 1-GB of RAM will cost about another $100 if I go with that. I think I would like to try the RAM I already have first and see how it performs. After all, I know it works.


I was interested in this board because it has both AGP and PCI-E graphics slots but all the bad user reviews on it scared me off.

Its a fine board, it just doesn't overclock that great. Mine only runs at 2370.(X2 3800)
