AutoCAD Build: i7-990X + GTX 480 or i7-970/2600k and (2) 580's

For work, we are looking at a new system for AutoCAD 2010 and HyperMove 3D rendering/Animation and budget of ~$3200 US. After a ton of research I think that we're down to 2 options, but I'm not sure which is better.

So, which direction do I go with? Either option is to be paired with 24GB RAM and an SSD.

OPTION 1 (More Cores, 12MB)
i7-990X
GTX 480

OPTION 2 (More Cores, 12MB but a little slower)
i7-970
GTX 480 and a second SSD

OPTION 3 (Less Cores, Newer Architecture, More Graphics Horsepower)
i7-2600k
GTX 480/580 in SLI (depending on budget)

EDIT: Is 24GB RAM overkill?

Thanks!

  1. The older hexcore is the better chip in multithreaded rendering , but not by much

    And over clocking the 2600K should nullify the difference and give you the latest hardware with the longest period of hardware support .
    so

    2600K
    badass cpu cooler that will let you OC to 4.5 GHz and not make a lot of noise doing it . Maybe a Scythe Mugen
    A Z68 motherboard
    As much RAM as you can stuff in to it
    And The best Quadro graphics card you can find

    Thanks for the feedback. As its stands, we're just about maxing out our budget.

    So in your opinion, if we had to cut back to say 16gb RAM, reduced the CPU outlay by going to the 2600k, we'd be better off going for a better quadro with more VRAM than the gaming cards can offer?
