Getting a gaming PC isn't worth it just for rocksmith, but if you have the cash, a PC is definitely worth it, I recommend building it yourself, it's a lot of fun, I learnt a lot and I can pick exactly what parts I want. :) Just at the end of my patience with xbox and most games are released in PC format anyway. Like I dropped Sony, I have no hesitation dropping xbox. Build one??? hmmm.....if you had a DIY build, did it cost much compared to buying one off shelf?
