Danica,
Clearly you must recognize from the results you've posted as well as from the response of the audience that something is clearly screwy with your claim. First and foremost, your fellow posters have (less than) kindly pointed out that your benchmark is hardly optimal. (though I should add here for the benefit of the crowd that it's certainly doing a good job keeping me amused - keep up the good work) Secondly, and perhaps more importantly, there is some information that you posted that simply doesn't jive.
You've listed essentially equivalent timings for your benchmark operation for a number of processors - a number of processors that decidedly do NOT have equivalent performance capabilities. (about 33-34 seconds for all of: Intel C2D6700, AMD 4600, C2D6800, AMD 4800) It looks like there may be some overclocking involved, but that still doesn't explain everything - if nothing else, specifically why the 4600+8% and the 4800+10% are exactly the same, plus the fact that overclocking didn't help your 4600 - not kosher, my friend. Combine this with the fact that there is a clear discrepancy between the lower end processors, and then all of a sudden you get to a plateau with the higher end stuff and..... well, let's just say this goes a long way to explain everybody's sarcasm.
So, your test is clearly bunk. But not worthless. You may have inadvertently stumbled across a common bottleneck that might be worthwhile to get out in the open so other people don't run into the same problem.
Now, some people have suggested that the DDR2 vs DDR RAM may be the issue. I kinda doubt it, but eh, I've been wrong before. It does look like, from the timings you've posted, more RAM certainly helps the cause. But still, something isn't right.
My suggestion is you look at the pagefile as the potential culprit. My hunch is that Adobe is writing things to the hard drive to use as virtual RAM instead of running information through your regular RAM. You're limited to the speed of the hard drives which, while fast, aren't nearly as fast as RAM. This would explain why everything plateaued - all your experiments are using RAIDed 150 Raptors? If this is the case, your performance issues have nothing to do with the power of the processor. They have to do with the fact that your processor is being lazy because the rest of the computer can't keep up.
Now, eliminating this bottleneck is not something I am an expert in by any means, but I have toyed around with it in the past a tiny bit. My suggestion is this:
Delete your Windows pagefile (set virtual memory to zero) and try your test again. This way, everything is going to run through your RAM instead of your hard drive.
Mind you, I'm not the end-all be-all of knowledge in this department. I seem to recall reading somewhere that Adobe likes to load things into the pagefile, so you might just want to reduce it a lot instead of setting it to zero..... However, you do have 4GB of RAM..... But I'm still curious if your computer is recognizing all of it. I've heard that Windows (regular Windows XP - the 32 bit variety, not 64 bit) doesn't recognize that much RAM, or you have to do something special - I forget. Whatever.
Anyway, run the test again and make sure that your hard drives aren't a bottleneck. Then please post your results again because if I'm right, I want to bask in the glory, and if I'm wrong, I want to know it because I'll have learned something interesting.
Best of luck.
