the i5 dual core 4gb ram and pny 460 will play wow max settings ... everything else doesnt really matter .. get a 7200rpm hdd and then just add the stuff u like.... main cities like org,dal,stormwind for some reason load from the hdd so the faster the hdd the better you will be in big cities.. dont ask me why.. i just know b/c of reading on the wow forums from a gm ... but to sum it up .. that pc is perfect for what u want
