Architecture pc build between 1000 and 1200

Hello,

So this will be my first build and I appreciate any insight i can get. Im looking on building a pc for my work, predominantly architecture. (3d software, rendering, walkthroughs, photo editing)

Approximate Purchase Date: the closer the better

Budget Range: out the door (1,000-1,200)

System Usage from Most to Least Important: 3d Architecture software (Revit, Rhino, Max, grasshopper) Rendering, Walkthroughs, photo editing, surfing, movies and music, maybe gaming.

Parts Not Required: monitor

Preferred Website(s) for Parts: no preference, other than it being all from the same site

Country: US,New York

Parts Preferences: I would like it to have a 120 ssd for programs and OS to run off of (fyi: OS I will receive from my school so this is NOT included in the price) plus 1tb harddrive for primary storage, also im looking on upgrading to a bluray.

Overclocking: NO

SLI or Crossfire: dont even know what this is.

Monitor Resolution: I should mention I plan on running dual monitors for multitasking. Not sure what would be best, this will come later

Additional Comments:

I've seen some decent builds for 1,000 on toms, custompcreview, and newegg but these r technically for gaming so before i purchase something like those I wanted to get some outside advice..

Also my current desktop is the old Dell e310. 6+ yrs old. Looking on Dells website you can get what looks to be a pretty robust system for the price point I'm looking at. XPS 8500 media desktop. Very decent specs i-7 3rd gen, 12gb ram, nvidia graphics, 1tb... Why is it people i talk to say "trust me build your own". overall I have no complaints with my old dell and I gotta say they have pretty attractive deals...

Thanks much,
Rob
