Tried this from 2 different sources and is not working for me. I have a M3i Zero GMP-Z003 card and now it shows as a different game but freezes when I select it on my ds lite and on my childs dsi xl with 1.4.4 on it, at least that what I think is on it.
I believe the GTX 560 is only capable of doing 2 way SLI http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-560/specifications. I better recommendation would be a GTX 670 and if your budget allows getting 2 GTX 670's in SLI
Intel Core i5 3570K 239.00
ASRock Z77 Extreme6 Motherboard 189.00
Palit GeForce GTX 670 2GB 439.00
G.Skill Ares F3-1600C10D-16GAO 16GB (2x8GB) 109.00
Noctua NH-C12P SE14 75.00
Samsung 830 Series 128GB SSD Retail Box 129.00
I kept everything else the same as you had it and the total was $1733
