Precision 390 with Quad Core CPU

It is a very quiet system with the qx6700 and q6600 considering those CPU's are hot.
I have to be within a few feet to even hear them while running.

It won't with the 390.
If you get the q6600 it will be even quieter than the ones I see with the qx6700 because they are hotter than the q6600.

I am sure you will be pleased with the 390. It is a great system IMO.

First off you can't get the PWS 390 with a Xeon CPU at all. You would have to move up to the 490 or 690 both of which are dual socket Xeon systems and cost a lot more than the 390. What do you do with the PC? The 390 is Dell's entry level workstation and has the Intel 975x chipset and uses ECC RAM and pro graphics cards. But to answer the question no difference. The 490 and 690 use the Intel 5000 based workstation chipset and Fully Buffered DDR2 ECC which has really high latencies compared to the 975x memory access so even though most quad Xeons are on a 1333MHz FSB the difference in real performance due to RAM differences is not much comparing same amount of RAM and close to same speed CPU's and cores.

It supports up to 667MHz and you can buy it with 667 so you might as well unless like you say it is too much compared to after market then just get the smallest amount.
See if you can find Axiom memory. They are less than most brands and guaranteed to work in the Dell systems.
