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.

Many Thanks

Couldnt find a Xeon so just went for the 3960X.
2 way SLI 680s for awesome performance.

This is my try at a ~$4000 system.

I'd go with 670 instead, in three.

Mobo doesnt support 3-way.

O.O

Thought it was 2. PCPartPicker had no more options to add in another GPU.

Three 670's would work better.Should cost about the same.

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

:)  Thanks

After hours trawling through the net I decided to go down the Supermicro route for the machine.

X9DAI LN4F+ motherboard
2 * Xeon E5-2643 (used cpus only way I could get below 4K)
ASUS GTX 680 CUII
1200 W Corsair PSU
4 * 16 GB ECC 1600 RAM
256 GB Samsung 830 SSD
Lian Li PC-V2120 Case
2 * Noctua NH D14 coolers

Thanks for your Help :sol:
