^ Agree kind of. It is strongly dependent on your workload. If it is only slight 3D modeling, the saved cost is better put for the GPU.

Gives you much more bang for the buck.
Some justification for the board I suggested. Z77 has 0 performance increase over Z68. Gen3 gives you PCI 3.0 support like Z77 so yep. USB 3.0 controller is still performing the same, and you save money instead. Plus you get the ability to still SLI/CF at 8x/8x. Better than most Z77 boards of the same price.
