I need the BEST FSX system money can buy, and need your help

I am looking for the absolute BEST machine money can buy, with its primary function to run Microsoft Flight Siumlator X.  This is what my Dell Representative has given me:

Base Unit:
Dell Precision 690 Mini-Tower

Quad Core Xeon Proc X5355 2.66GHz, 2 X 4MB L2 Cache 1333MHz
2nd Processor,Quad Core Xeon Proc X5355,2.66GHz,2X4MB L2 Cache, 1333

Hard Drive:
146GB SAS Hard Drive, 1 inch (15,000 rpm)
146GB SAS Additional Hard Drive, 1 inch (15,000 rpm)

Hard Drive Controller:
C11- All SAS Hard Drives RAID 1 dual for 2 Hard Drives

Operating System:

Like I said, I want the BEST machine money can buy me, unfortunately I can only purchase business machines through work.  I am hoping someone can provide me with the BEST video card for gaming (If this is already one) or any other thoughts or areas of which I could improve this system.  It is for the owner of my companies father, and want it to be PERFECT.  Thanks in advance for your help!!!

I would skip the Dell and get a Alienware to start with. They will bulid you anything you want.

On the up side to that, When its time to upgrade Alien will do it. Just send it in and they send it back with warranty.

Hello  Havis-Shields:

That system sounds like pretty serious overkill - a great server that should run Filght Sim pretty well.

Dell makes system specifically configured for gamers branded as the XPS series.  These include quad core CPUs and SLI graphics - you might want to check them out on the Dell site: search on 'extreme gaming systems'

ECC RAM is good for servers, but isn't the fastest RAM out there.  Check out the premium models from OCZ, Patriot, Corsair, Mushkin, or Kingston, unless the motherboard requires ECC RAM.

The nVidia Quadro FX cards are good for CAD and OpenGL, but not for 3D gaming.  One of the top performing cards right now is the nVidia 8800GTX, but it depends on the game: http://www23.tomshardware.com/graphics.html?modelx=33&model1=519&model2=547&chart=204
Another good one is the ATI Radeon X1950XT, but you would need two in CrossFire mode with a CrossFire motherboard to beat the single 8800GTX.

The xps 710 would be the best from dell (but its not a business system).For gaming the dual quad procs is not needed. I would go with the dual 5160's (dual core 3.0Ghz). For the video 2xquadro fx4500's (thats $2,690!!!!!! i could build a sweet gaming rig for that much) go with the cheapest option the nvs 280 and just spend $1200 on 2 8800gtx's(in sli which the 690 supports) and that will outperform the dual fx4500. Quadros were designed to be a workhorse for programs like CAD, and Maya and they will play games but not as well as there Geforce counterparts. Also make sure to get the 1 kilowatt power supply to power those gtx's. That would be a sweet top o' the line gaming rig. Also with the monitors in sli you'll only be able to use 2 monitors even though you'll have 4 ports on 2 ports will work in SLI.

PROCESSOR      Intel® Core™2 Extreme QX6700 (8MB,3.2GHz Factory overclocked)
MEMORY      4GB Dual Channel DDR2 SDRAM at 667MHz - 4 DIMMs
VIDEO CARD      Dual NVIDIA® GeForce® 8800 GTX, 768 MB
PHYSICS ACCELERATOR      AGEIA® PhysX® physics accelerator

That is what my concern was, my rep can only quote me business systems.  With these Video Cards could I run 3 monitors?  What about this core system?
Havis-ShieldsAuthor Commented:
Can I put three cards in the machine to achieve the ability to run 3 monitors?
Havis-ShieldsAuthor Commented:
In addition what are your thoughts about using VISTA to run the machine?
jamietonerConnect With a Mentor Commented:
You could run 3 monitors but you wont be able to run in sli mode. The PhysX card wont be necessary FSX won't use it.
jamietonerConnect With a Mentor Commented:
With what i have seen of Vista so far i would stick with xp pro if possible.
CallandorConnect With a Mentor Commented:
Run two 8800GTX's in non-SLI mode; each have dual outputs to give you 4 displays if you want.  The QX6700 is a better choice for gaming than Xeons, since this cpu has an unlocked multiplier, which lets you overclock if you want.  If you do, get a Zalman 9500 cpu cooler to go with it.

Tell the Dell Rep that you need a XPS 710 H2C.  It is what every gamer wants, it's what I would want if I had 6 grand.

Tell the Dell Rep that it is absolutely a business system.

Why are you playing hardball with the Dell Rep?
Do you want a big fat Christmas Bonus this year?  Yes.
Do you want to have to go visit the bosses Father for PC problems?  No.

Convince the Dell Rep that it is really in his best interest to get you this system... end of story.
Then mention something about Alienware having a great system and it's ok if he can't get it.

I'll bet you 500 points if you put the screws to the Dell Rep he can get you this system, tell him its for the marketing department.

Change to faster RAM

Overclocking in Dells is fraught with problems but the QX card is a good idea

***Absolutely stay clear of Vista for gaming***  
XP SP2 - if the box has Vista ensure all the components are supported with XP

No one has mentioneed the screen.  
Get a low refresh, Dell have some 5ms monitors on offer at the moment but their standard monitor is around 22ms, might not sound much but is certainly the difference in getting a headshot once you've landed and changed games!!
Havis-ShieldsAuthor Commented:
UltraSharp 2407WFP - 6ms - Which I want to run the main image
UltraSharp 1907FP - 20ms - I had plan on making them run the electronic controls - Not intese
