As a Mac user, it might seem a bit strange to post this.. but my son works business sales at Dell, and he might be good to deal with (save you money). If you call him, tell him where you got his name. His info is

Feedback from my Dell dude son...

Yea it would make a huge difference. He is talking apples and oranges between a 5 year old system and a new T3500. The new T3500’s have the Nehalem chipsets (like the new macs J ) as well as ISV certified Open GL 2.0 graphics cards, DDR3 ram..and on and on. Also comparing a new Xeon quad core to a pentium 4 is like comparing a bicycle to a Ducati motorcycle. Even though the clock speed may appear lower, you are running a completely different architecture and even beyond that..4 cores vs 2..maybe even 1 core on an old Pentium 4.

I can do huge discounts on those too J

Rick,
Thanks for the link to your son at Dell.

Rick,

it may be too late, but I'd remove your son's email ASAP before the spambots eat him. If you want to distribute it, do it by PM or word it in a way the spambots don't understand!
(I've been bitten by that myself)
