Overkill! Why do you even need a high end video card? A very low-end card will do you just fine...
I have not used Maya, but i am familiar with some of Autodesk's other programs such as 3D Studio Max Design and Revit Architecture 2011, when it comes to rendering images its all done by the CPU cores.
I have been using 3DS Max for about 2 years now and just recently bought my Sig Rig. Only ever used the computers at my College (Dual Cores). I went from rendering images in ~18-24Hrs to less than 2Hrs now with my 6 cores at 4GHz. so best to go with an i7 970/980 or 2600k for '12' cores. I think the 990 is overpriced.
An SR-2 board with 2600k's would be insanely quick!
An SSD is not needed for this kind of work but will make boot/load times much much quicker. Wont see much diff in rendering
the GPU is only used for the viewports on the screen, which can still be very taxing. a Single 6990 should be plenty.
8-12GB of RAM will be plenty as well.
IPS monitors FTW! pricey but well worth it!
SR-2? 1366? is that the same as 1155?
SSD rendering? you use the SSD to make programs go faster, not render to the ssd, so with a budget of over 5 grand, why not grab an ssd?
GPU? never heard of cuda processing? well, you sir, have been missing out.
IPS? yes. IPS. go for it!
