A couple of minor quibbles, the stats you listed for processor are only if you decide to go for an AMD processor.
With FrostBite one of the neat things is they have the technology for Mantle and its designed to help under powered processors offload onto the GPU. They have used it with Battlefield 4 already, but I haven't heard of another game engine that works with it.
Bit late on this, but you're right. Generally statistics read however people want them to... But it's really all we have to ballpark it for now.
Mantle is in a lot of ways similar to the HUMA system the PS4 uses, except since the PS4 uses it's DDR5 for both system and graphics, it doesn't actually have to copy the data it's trying to offload to the GPU reducing the cycles.
Either way, offloading Processor functions to GPU is a great thing because the GPU's do brute force tasks like physics and AI really well.
