hi people. my friends brother wants a mac to learn graphics and record music. he looked to me for answers and i set him up with the dual 1.25 system and told him it should last him about 3years before he would want something else. i told him that a 1ghz single processor would probably last him two. since its new to him he wants to start with the single 1ghz processor system. BUT for five hundred bucks more he can have a DUAL 1.25 so my question is...will he get good use out of the single 1ghz for music (reason2 _ protools LE) or will he need the 1.25 DUAL to be a happy mac switcher? his current system is a four year old pc Soooooo do you think he would be happy with the single processor running the music applications? or should i let him know that for $500 more dollars he could get a way better system....the dual 1.25. thank you.
