Like the rest of you, I spend some free time pricing out new systems and contemplating whether it is better to go with a desktop on steroids or to just opt for the workstation with the dual Xeon processors, dual hard drives, etc...
The best site that I have come across as far as pricing out the options(one that has all top of the line components: motherboards, processors, hard drives, video cards) is
www.monarchcomputer.com Note that I have not ordered anything from them yet, but they do have a good Reseller Ratings and I am very impressed with the products they offer...I also have noticed that they now offer the Matrox Parhelia video card which was just released as a retail product as of June 30th....
I am going to probably opt for a desktop with Rambus PC800 RDRAM as I have read numerous articles on how the RDRAM is superior to all else...They also offer Corsair RDRAM, but I think the 1GB of Rambus RDRAM is probably a better choice...The prices are high on alot of the components, especially some of the better cases like Lian-Li Aluminum cases...But either way it is nice to see a site that has all of these parts categorized...From there you could probably do some more leg work and find this stuff to put together or to hire a guy to do it for you, if you so desire...
They also have a very extensive number of options for putting together a workstation(if you are really getting serious) with Dual Xeon processors, 2GB of RDRAM and a number of video cards like a Matrox Parhelia and a Matrox 550 for some flat screens...From what I see this site probably could give you a really top of the line workstation for a better price than some of the sites that have been mentioned that cater to the trading firms who go for the high end stuff for putting together 4-8 monitors on a single workstation...
Feedback is appreciated...
