Throw your $$$ at the PSU (which you just did! ), and GPUs. Get 2x the dual cards - either (2) NVIDIA 590 or (2) AMD 6990 GPU cards, so you effectively have 4 GPUs. You will easily have a rig that crunches well over 1Mil per day... on 1/2 your budget.
If you really want to spend $6K to help out the team ... BUILD 2 OF THESE MONSTERS!
I would advise taking a couple steps further if max credits is the goal - find a mobo with 3 PCIe slots triple spaced - put the cheapest CPU and RAM in there and don't crunch on the CPU. Only use them to feed the GPU. Pick up a crapton of GPUs in the "sweetspot" o' money. A 6950 is ~$230 right now three in a box (caseless if you're adventurous) and you can probably do 1M/day on ~$1000. Multiply that by six. Then get DrPop to pay the power bill...
