The ultimate replacement CPU chip for the Classic Amiga today is a Virtex 5, XC5VFX***T FPGA!
Why?
Onboard 550MHz PowerPC 440, Gigabit Ethernet, PCIe 2.0 (not enough lanes for gfx card :-(), SATA II 3G, DDR2, enough FPGA space to easily implement a 680x0 CPU
Ok so they are several hundred dollars each
