i think you may want to re-assess if the x5000 is slow.... just set mine up and already i notice a big big difference compared to the Sam 460..... even Timberwolf is usuable ;-)
webpages on Odyssey load very quickly... really impressed so far with this machine :-)
Slow is relative. Compared to my 8-core Ryzen 1800X (3.6 GHz base, 4.1 GHz turbo), which cost about €700 for the motherboard+CPU, the X5000's dual-core CPU (one usable core in AmigaOS) at 2 GHz is slow by any metric. It's perhaps as powerful as the Snapdragon SOC in my phone.
Still, it's the fastest "Amiga" in the world, so by that definition it can't be slow, and it certainly should be faster than the SAM 460 that came out 7 years ago. So if you really want the fastest AmigaOS 4 machine available, this is it.
