Some bull%&$#?@!%&$#?@!%&$#?@!%&$#?@! here, but also good points of views.
It doesn't make sense to buy X1000 just for playing old amiga games. They are emulated and that kind of emultion doesn't require much. Even Sam 440ep can emulate A500 without a problems. So if you are not a rich man, don't buy X1000 just for old games.
If you are planning to use old pruductivity software that is a different thing. 99% of them works very well with Amiga OS4 and really fast when comparing to any 68k Amiga.
What would I suggest to you is buying a second hand Sam 440ep or ep Flex. Really nice little mobo with very high quality. With that you get NG Amiga very economy price and you can see do you like it OR not. Only extra thing is whdload key file, if you want to play whdloadized games.
If you have used Amiga OS3.5/3.9 you most likely like it.
What is bull%&$#?@!%&$#?@!%&$#?@!%&$#?@! is that playing old 68k games would require some effort. OS4.1FE installs RunInUAE when you install OS, so you can start those games just double click even if they are NODOS disk images. With Amiga OS4 you will get working emulation eviroment as it have a required kickstart files, os disks, etc licenced. Unlike other NG machines.
As a bvonus Sam 440ep is very well supported by OS, ithas a all needed drivers, like 3d etc.
