The DIY PC route is still going to be more affordable. If we go the Ivy Bridge E route and opt for a Core i7-4930K, you get more cores than either of the options above for around $600 for the CPU. Adding in another $330 for a motherboard, $180 for 12GB of DDR3-1866 memory, $1400 for two W7000 GPUs and $220 for a fast SATA SSD (Samsung 840 Pro) we’re at $2730 for a configuration that would cost at least $3499 from Apple. That’s excluding case, PSU and OS, but adding another ~$350 takes care of that and still saves you some money. As the AnandTech review points out, you're looking at $2700ish if you opt for hardware that is apples to apples comparison... regardless of whether you went with hackintosh, Linux, or Windows.
