Any modern computer with 4GB or more of memory and at least a dual-core processor is OK for JPlay, but more power and more memory are better. Windows 8 helps too because some of the latest JPlay features can only be used with it. The less you do other things with the computer while it's playing music the better, to avoid clicks and pops and slooow browsing. All of that because JPlay heavily tweaks Windows to give priority to sound. I have found that using Fidelizer before starting JPlay helps even more, but then you can barely use the computer for anything else but music until you reboot. A dual-PC arrangement is even better.
