Many I ask why a $1500 PC for Minecraft. You wouldn't even need a single GTX 770 to run Mincraft. The SLI will probably get you more than 5000FPS, I don't think I can see that...
But still there is no need for a 5930k. I also put in 8GB because that will last him till DDR4 goes down in price! It doesn't make sense to pay a premium for RAM right now that he is not going to use.
