I know we are not really focused on X64 yet, but I must admit to being really jazzed up about AMD's new Ryzen 7 CPU.
Sure, its a little more expensive than low end processors, but its a lot less than a higher end i7.
AND it benchmarks really well (16 freaking threads guys).
Combine that with some of the great gpus that AMD has been introducing, and this is a killer combo.

I would love to run MorphOS 4.0 on something like this.
