Interesting perspective, my own is the opposite.. Discrete GPUs have a thermal advantage, because they don't have to share heat-sinking capacity with the CPU.. My Graphics card certainly spews out _A_LOT_ more heated air than the CPU, and on full load, the entire system is practically a space-heater.. Having more physical room for heat-sinking is an advantage in this scenario. I see the same advantage with power. A PCIe card can more or less ignore the supply from the socket and decide how many various molex plugs they need. There's already dedicated PCIe plugs, and nothing prevents the addition of more, except physical space on the wide edge of the card, the capacity of PSUs and the physical challenges of transporting 99.manynines of that power away as heat.
