UNLESS you use your dual opteron or dual xeon setup for specific applications like rendering, P4 3.2HT+ will be faster than a dual xeon 2.66 or dual 1.4 opteron setup in gaming, decoding, encoding, mathematical calculations.
A dual setup will greatly benefit from workstation and rendering applications and even at that not always faster than a single fast cpu.
I understand you are thinking of getting a dual 2.8 and dual 1.6 opteron setup but still then for the same money you can overclock a 3.4ghz p4 to 4.0 and it will ABSOLUTELY crush any of those setups. It's always been a myth that a dual setup gives a huge increase in performance because it does not! Only for specific uses.
I don't even want to mention getting an FX53 or 3.4ghz P4EE setup and overclocking those because they will leave the dual setup in the dust and still cost less! And there is no way in the world a 4ghz p4 with raptors and some solid ram loses to a dual setup with slower speed ram and normal non-10,000rpm hard drives. And if you want to get SCSI hard drives they better be the top 2 ranked on storage review cuz those are the only 2 faster than the 74gig raptors for normal applications besides server usage (will your rig act as a server?) Of course a SCSI card and SCSI drives cost a lot more to start with. If you start adding up all these costs, you'll quickly find yourself far exceeding $2000US. I don't want to mention again but an FX51/53 with an Nventiv setup overclocked to 2.8ghz will make the dual 1.8ghz Opterons cry in pain in every day applications. The fact that you will be able to use the Prometia or the Vapochill setups for the next 5-10 years like i previously mentioned will also give you an edge by helping you to continuously stay in front of the market.
Don't believe me? See just how well a 3.2ghz P4 HT stacks up against the dual 2.66 xeon and dual 1.4 opteron setup.
Just read this
Review here. And also a dual setup is plagued by instability as described in this
Review. Yes a 1.8x2 opteron setup will most likely be faster than a 3.2ghz p4 but for that kind of money you can easily build a faster single processor system. Don't forgetNow I have never used a dual setup but looking at the benchmarks, there is no way a 4.0ghz p4 will lose to a 1.8x2 opteron unless you use very specific programs that thrive on a dual setup which don't seem to be the "normal" applications tested in the article that we have all heard of before. One thing is for certain a single high speed cpu is better for gaming and there is no doubts or ifs about it. So again it all depends on your usage, and how much you are willing to spend and so far you have not explained thoroughly what kind of things you are going to do with your system.
In Summary:
"Workstations are typically very specialized machines, so you'll have to decide for yourself which of these platforms makes the most sense for your particular needs. If you are faced with the choice of a top-of-the-line single-processor PC or a lower-end workstation-class system, you can see from our tests that the choice may be quite a dilemma. Clearly, in most tasks, the faster single-processor system outperforms a slower dual-processor workstation. However, for tasks that are easily parallelizable, like 3D rendering, multiprocessor systems can be worth investigating." - The TechReport
So if you are going to get a 1.6+ x 2 opteron setup or a 2.8x 2 xeon setup, one can always make an argument for a faster single cpu than a 3.4ghz p4 (like overclocking it). So unless you overclock the dual setup or have specific needs for it I dont see how it's a better setup.
Look at it this way in a couple months you can get P4 on socket T or A64 on socket 939 giving you a cheap upgrade path and very fast performance. So all this time you'd be able to smoothly update the single processor rig making it faster and faster....while the other 2 setups will either sit there and age or require costly updates every time.
