Workstation Build Help

[la_gun_builder]

Hi, I'm new to these forums. I'm looking at doing my first build. I will be using this computer for AutoCAD Architecture, Solidworks, Photoshop CS5, Illistrator CS5, After Effects, Dream Weaver. I want to use dual 24" monitors. I also will be using the computer to stream/play HD video to a third 47" monitor, when I'm not using it for work. I do not know if I should get the P67 or Z68. I want the p67 for sli or xfire capabilities down the road, but I also want the z68 for SSD caching with SRT. If I go P67 I can just get a 120GB SSD to install my OS on. I want to keep this build under $1200. Any help is appreciated.

Here is what I want to include
-Intel i7 2600k
-16 gb ram
-2TB HDD
-60SSD or 120 GB SSD
-Blu-ray reader/writer

I am having trouble on picking a graphics card. I know the Quadro 600 will probably best suit me. I don't want to spend more than $200 on a graphics card, especially when it doesn't have SLI capabilities. Will this workstation graphics card be able to output 1080p on my 47" monitor? Would crossfire HD 6850's work just as good on a workstation as this quadro 600?

here is what i have so far

You might as well Get an AMD Radeon 6770 or 6850.

I think if you are looking into SLI or crossfire x in the future you should mabye get a beefier power supply.
