T shaves off performance for energy consumption so the K would be better performance wise plus you can overclock it.
Yes, but he's talking about the Alienware Alpha. The i7-6700T is the best you can put in there.
Other:
I don't see the GTX1060 listed for the Alpha so I'm not quite clear now what this question is about.
Do you already have the Alpha and are considering moving the i7-6700t into a desktop?
No I'm planning on using the graphics amplifier which I already have.
If so, I'd investigate what you could sell the Alpha for instead because that's an expensive machine to be ripping apart. I'd rather you SELL it, or at least the CPU and buy a full i7-6700K for the desktop.
