I have an opportunity to buy one of these pretty cheap. The downside of these is it's only 800 MHz FSB. The upside is the 4 MB L2 cache. Any thoughts on one of these for a dedicated cruncher?

Rosie likes lotsa L2 cache!!!

If you can get this "pretty cheap", I wouldn't worry at all about FSB. IMHO, L2 cache, RAM, and cpu speed more important than FSB.

Go for it!

The highest RAC I could find for a PD 925 (3.0ghz) is 472. This sounds like a dedicated cruncher, as the PD 3.4ghz versions hover in the high 500s. If it is a Dell, be aware that you will not be able to OC at all. The larger L2 cache is a plus, if you ever decide you want to crunch for folding@home. The smaller L2 of the 8xx series, and all AMDs, doubles the crunching time for the SMP clients. I'm not saying you should go to folding, but it's nice to have the option.

On the other hand, you can buy/build a pretty cheap Core 2 machine too, and get 2-3 times the performance of a PD 925.

Only you can tell if it's worth it.

Only if
1) You are getting it new with cooler delivered for less than $50.00.
2) It fits in your mother board.
3) Your mother board bios is ok with it.

You can get an intel core duo E4400 for $125.00 or the INTEL Core 2 Duo E6550 2.33GHz FSB1333MHz 4M LGA775 Retail BX80557E6550 Processor with Free Shipping for $170.00 * no tax *

These all have the same socket lga775 just check your bios.
The reason I keep mentioning the bios is becuase I tried to replace my pentium II with pentium d 2.8 on 2 of my pc's before I went to Vista but the mother boards bios' were not happy so I had to get new MOBs. I still have pentium d's.

Sorry, perhaps I misunderstood OP.

I understood that he was able to get the entire pc, not just the cpu, for "pretty cheap".

For less than $100, a functional pc with os and the D925, I would do it.

If OP meant the cpu only, then I would offer a different opinion, and suggest (as others already have) the Intel Core2 line of cpu's.

I had a P4D 3.2 system a while back that ran R@H 24/7. I remember that it got up to about 530 RAC before I had to return the system. It had only been running R@H for a few months, so I'm not sure if the RAC had leveled off yet.

The P4D's crunch pretty well - if you can get one for cheap, go for it.

That's the way I read it too.

As I mention before I have 3 Intel Pentium D 920 2.80GHz cpu's that I tried to use for my upgrade. I could give 1 to you if want.

I appreciate your generosity. I would definitely put it to good use as a full time cruncher. Is there a way I can PM you my address? I don't see a PM option on the Rosetta boards like SETI has on theirs.

I set up an email account for it. I do not know if it is case sensitive so use all lower case.
