I'm ordering Revit workstations from Dell. The Precision line seems to be whats geared towards CAD\BIM. The only processors available in this line are Xeon Dual/Quad/Six core processors. I've been reading that the i7 processors are the way to go. Dell only offers i7 processors in their Vostro line and while configuring the memory and video card options don't seem to give me the graphics adapters and memory capacity I need.

AutoDesk performance recommends: Intel® Core™ i7-2600 quad-core processor (3.8 GHz, 8 MB cache ) or equivalent AMD processor. In the Precision T3500 series the processors below are available. Will these Xeon processors below meet or exceed the AutoDesk performance recommendations?

Quad Core Intel® Xeon® W3565 3.20GHz, 8M L3, 4.8GT/s [add $510.00]
Quad Core Intel™ Xeon W3550 3.0GHz, 8M L3, 4.8GT/s, Turbo [add $310.00]
Quad Core Intel® Xeon® W3530 2.80GHz, 8M L3, 4.8GT/s [add $250.00]
Dual Core Intel® Xeon® W3505 2.53GHz, 4M L3, 4.8GT/s [add $50.00]
Dual Core Intel® Xeon® W3503 2.40GHz, 4M L3, 4.8GT/s [Included in Price]
Six Core Intel® Xeon® Processor W3690, 3.46GHz,12M L3, 6.4GT/s [add $1,730.00]
Six Core Intel® Xeon® Processor W3670, 3.20GHz,12M L3, 4.8GT/s [add $900.00]

AutoDesk also recommends for graphics, 2 GB (or more) DirectX 10-capable graphics card with Shader Model 3.

Below are the graphics card options available with the Precision T3500. Which of these will meet the AutoDesk performance requirements for use with Revit 2012? or should I just get the cheapest video card option available here and purchase a graphics card separately from another vendor like newegg.com? Can someone recommend a graphics card or specs of one that I could do some research on to purchase separately? There has got to be a few models that people have been raving about with good results? If so please post a link or provide me with some info, I'd really appreciate that!

Memory:
I'm probably getting 24GB but purchasing it separately as the cost with the system is an additional $1,660 and if I purchased the same Dell memory from Dell as separate items, it would cost me under $460. Which seems strange but that's what it seems to be.

With the above information provided, what processor and video card should I purchase to meet the AutoDesk performance Recommendations to run Revit 2012? Appreciate any suggestions.

Thank you!
