i7-900s vs Xeon processors - identical?

Watch the video for falcon trading systems at 3:35. These guys
seems very unprofessional with how they handle the PC's. That
guy's just holding the motherboard in his lap just snapping in
parts. He's not grounded (http://www.wikihow.com/Ground-Yourself-to-Avoid-Destroying-a-Computer-with-Electrostatic-Discharge ), or wearing any gloves, so his oily ass hands are getting over everything. Then you have the old man listening to his ipod, or maybe its his hearing aid, I don't know, but I love how its just dangling over the PC waiting to get snagged on something.

PASS!
 
It seems that from a price-performance perspective, i7 is a bigger bang for your buck for retail traders using desktops. Similar or better performance at a lower price. Unless you want to run your trading software on a server class machine.

What are the differences between the i7 and Xeon lines of processors from Intel? More importantly, which one is better for trading?

They appear to be identical. For instance, when comparing the specs of the i7-920 and the Xeon 3520, the specs indeed do come up identical. Does one processor meet the needs of a trader running 4-6 monitors better?

4-6 monitors doesn't necessitate a powerful processor. If you needed something powerful, you likely wouldn't need to ask here. The guys here pushing i7s+ may very well be wasting your money.

My first 4-monitor rig included a TV tuner... ran on a P III, with 4 MB RAM video cards... video requirements for nearly all of today's trading isn't any greater.

What are you superstars doing with 8 gig ram?

I run 4 gig, multiple apps , and use less than 60% ram on any given day.

You just like unused ram sitting around?

PS Why are you turkeys buying slow ram when 1600 or faster is available?

I have 36gb in my T5500 with dual w5580 cpus... What do you care what we do with our RAM? Perhaps people do other things than just trade with their machines.

If you don't mind my asking... (1) How much did 36GB of RAM cost when you bought it?, and (2) What is your peak RAM usage?

The box was about $7,500 new and its ECC RAM so its pretty expensive.

So 36GB would cost you roughly $1k. You can get non-ecc RAM for much cheaper though.

Peak depends on what its used for. Most of the time it only uses 1-3gb but when I run simulations overnight it can get up to 28-29gb when it loads all of the parameters into memory. So probably 12 hours a day its loaded up and 12 hours its idling at 1.5-3gb used.
