@ cpaek72
first off welcome aboard:)
The A1-500 (aka RedOne 460) is a great sturdy machine and many users are reporting that AGA games are running smooth on it especially with the new E-UAE JIT which was recently released in RunInUAE. If you want to get the current king of AmigaOS machines then spend the extra money to get it along with future dual core support etc. If you want to wait and see what the new upcoming X5000's will cost and be like then you have that option as well.
Either way it's a fun time to get back into Amiga both classic and NG for sure!
@ amigakit
you mean with OS4.1FE the full 4GB ram can be used now? I just recently installed FE and my WB is still reporting 2GB?
