LOL - Actually, I can see what this thread is really all about.
Dad's "business" computer is a piece of crap that he uses to download his MP3's and surf the web. And oh boy does he wish he had his own PC. But, there's no chance of that happening so he thinks he can upgrade dad's PC with a new Processor and all will be well.
Dude, forget about your dad's PC. Start saving your pennies and build your own PC. Also, buy any A+ Certification Exam Guide written by : Michael Meyers. After you have studied up and collected all your bank. Start building "YOUR" rig! And buy a fingerprint reader so your dad can't use it... LOL
