Do you wan't an epic PC that will last you for a nice time with high end performance?

What activities will you do on the PC? The CPU is overkill for gaming. You can get an i7-5930k for half the cost. I understand you want to future proof your build, but even a Skylake i7-6700k and 2-way SLI will be plenty enough. 4-way SLI is overrated and most games don't scale well on anything more than 2-way SLI.
