hopefully i can provide some feedback on the graphics cards: when you spend a ton of money on the graphics, always find a card that has a single powerful GPU; more GPU's != (not equal) better performance. There is a benchmarking property called scaling where the 2 graphics cards will never provide 2x performance, it will always be less. In simpler terms: 1 card: score = 10000, 2 cards: score 15000 (this is just an example but it happens frequently with benchmarking) source: GeForce GTX 700 series SLI review: GeForce GTX 760/770/780 in SLI and 3-way SLI - GeForce GTX 760 - Scaling | Hardware.Info United States So far your choice of components are perfect: LGA 2011 Motherboard (ASUS, i personally think they make the best mobos) + LGA 2011 CPU (3930K, my dream CPU) + 2400 RAM (probably need to set to run in XMP) The power supply, like some people have mentioned is excessive and will just cost more in the long run but its great that you got modular. Just a fair warning with the hard drive, I had bad experiences with barracudas (I worked in IT). Reliable drives are WD Red and Black (never get the blue and especially green) Hope any of this helps. Have fun with your future Rig! I also forgot to mention. Depending on what you will be doing with SSD, a feature called TRIM can be advantageous to you. If you edit pictures or constantly move a lot data around the SSD TRIM can help boost performance. Just food for thought
