Or one could take an expensive high-performance Intel chip like a i7 6700K 4GHz (4.2 "turbo", overclockable) ~$400+motherboard+graphics etc.
Assuming one can emulate a 68k at 1/4 the native performance one will get a virtual 1GHz 68k processor...
I was thinking more along the lines of a Hard Copy chip. (That's a one-time programmable FPGA.) HardCopy chips of previous generations could clock at 400 MHz or so, so by the time the bugs are worked out of the Apollo core, there may be a newer generation of HardCopy chips that will go faster than a conventional Cyclone 4.
Also, 1/4 native perfomance on an i7 sounds ambitious, especially since each core of an i7 is dual-threaded making the single-threaded speed roughly half that of the core.
