FWIW I would go with the duals.

3 weeks ago I tried a setup using an Athlon 750 with 384 meg ram, good fast 7200 rpm drive and Win2000. The system was very fast, without a doubt noticeably faster than anything I have used previously. But in actual use during the day, I found the CPU utilization to peak just about as much as my old system (which was a pretty good system) This is my main trading machine. I run two intensive java apps on it for my trading. Qcharts for Level 1 quotes, charts T&S and Island display, and an order entry / Level 2 java app for my actual trading to my broker. These programs are written extremely well, but during a fast market or on a hummer of a stock (like the PALM IPO) I could max out the CPU pretty easy. When it was maxxed out I got lagged info. This is mainly due to the current Microsoft Java VM (virtual machine) software not being all that robust.

So the new Athlon wasn't all that much better, so I built an ABIT BP6 with dual 550's and Win2000. It performed much better than the single CPU Athlon. I haven't been able to max out the CPU's for more than a split second. The Microsoft VM does take advantage of dual CPU's. I watched the PALM ipo with a full Level 2, 1 minute tick charts, Island display, and T&S. Both CPU's never really got over 40%. I am on DSL, so my bandwidth wasn't the limiting factor either.

A Long story with the moral being: Build a dual CPU system.

IMHO, dual CPU's are of great worth and are generally under-rated, mostly by those who don't use them. :-)

I hope this rambling helps someone.
Good Luck
Dan
