I am looking to build a powerful dual cpu number cruncher for some digital photo based landscape geometry reconstruction and need some advice. I have been trawling the folding sites and overclocking forums for some pointers and have settled on a loose configuration.
As a base I need a 2 cpu motherboard along the lines of the Asus Z9PE-d16. I need high CPU speed so a single Xeon E5-2643 at 3.3 GHz seems best bang for buck to start with. I will need at least 64 gig RAM initially before expanding to 128 with the second CPU. I was hoping to use non ECC RAM such as 8*8 GB ripjaws but they only seem compatible with the Z9PE-d8 (8 dimm equivalent motherboard). GPU will be a GTX 580 or 680 to start with for the high CUDA cores for GPU processing, before a second is added. The rest is incidental for me as I will scavenge from my old machines. Has anyone had experience with such a system or this motherboard, and can it support the non-ECC RAM.
I have also noticed a few people are running windows 7 64 on the motherboard can anyone confirm if this is possible. Have no issues with running Linux but have heaps of GIS based software packages that will make this problematic.

Couldnt find a Xeon so just went for the 3960X. ---> I am looking to use two processors and expand the RAM out to 512 GB I cant do that on a 3960X
2 way SLI 680s for awesome performance. ----> 670 seem to be the sweetspot for price/performance
After hours trawling through the net I decided to go down the Supermicro route for the machine.
