Wow, there's a *lot* of bad information in this thread.
First of all, there is nothing *wrong* with AMD processors. They do not "crash and overheat," as has been mentioned by some know-nothings. Arguing between Intel and AMD is like arguing between Chevy and Ford. They are practically exactly the same, but everyone has their own preferences, based on personal anecdotes, and what-not. Do not let quality become an issue in your decision, as there is no difference between the two. Also, the Opterons function perfectly well as 32-bit processors, which is all you should really be concerned about, as a 64-bit Windows OS as well as 64-bit versions of your software are still in the future and you seem to be in need a hardware today. So while the Opteron's 64-bit abilities are certainly not disadvantages, do not factor on them too much as an advantage, either. Make your decisions on the 32-bit performance of all your options.
Anandtech is widely regarded as a reputable and honest hardware reviewer. They have some well-executed set of benchmarks pitting dual and quad Opterons against dual and quad P4s.
Web-serving:
http://www.anandtech.com/IT/showdoc.html?i=1935 Database:
http://www.anandtech.com/IT/showdoc.html?i=1982 Neither of these benchmarks fully addresses content-creation performance, but other single-CPU benchmarks have. You should be able to find a plethora of these reviews/benchmarks from Anandtech as well as several other review sites. You should always gather as much information as you can from a wide-variety of sources, before making any purchasing decision.
Now, for my *personal* opinions on the matter. *I* would probably go with the Dual Opterons (244 : 1.8GHz : ~420USD/each) over the Xeon
3.0GHz. They are equivalent in price, with the Opterons offering
slightly better performance, due to it advanced memory architecture, which would probably play a large role in your applications. And you still get a *small* bit of future proofing with the Opterons, due to their 64-bit abilities. You can pretty much bet that you won't get any additional performance out of Xeons simply with software upgrades, but 64-bit editions of Windows and PS/UF could theoretically give you a boost, as they would "unlock" some of the Opteron's features, such as additions registers, etc.
Good luck.

Hi folks,
I am finally getting near buying a new PC to replace my ancient one, and I have some decisions to make.
My main use for it will be graphics, and both of the main programs I use (Photoshop and Ultra Fractal) can take advantage of dual processors. UF in particular depends primarily on pure number crunching, so CPU speed is the major determinant of speed. Its architecture is such that dual processors provide nearly twice the rendering speed of a single CPU.
I had originally thought of going with dual Xeons, say around 2.6 or 2.8 GHz, but I would be able to put something together with dual Opteron 64s for just around the same price. I haven't been able to find much on the net about dual Opterons, and I'm wondering about stability issues, etc. I'm not really interested in overclocking or anything extreme, and my needs apart from number crunching would be quite modest--I'm not a heavy gamer or anything.
For that matter I wonder if the 64 bit processors will really offer any advantages in the next few years in general computer use.
Another option would be to forget about dual CPUs completely and go with a moderately high end P4 or Athlon.
I'm wondering if anybody has any experience with any of this that they'd like to share, or links where I could find info on dual Opterons.
Thanks in advance,
Toby
