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? It cost a lot less, since you would be paying for assembly, there are a lot of good walkthroughs, I used neweggs one. You can build something pretty great for much cheaper then a manufactured PC. Putting it together is such a simple task that my 6 yoa could do it. Newegg and amazon are good but, if you have a microcenter or frys near you they are probably the best place to go. Microcenter almost always has a bundle deal where if you buy a cpu you get $40-60 off a mobo. When i did my last build I cross checked everything with amazon and newegg. Some items I bought off the web but, the cpu/mobo combo on top of their regular sales prices just could not be beat even after all the ridiculous CA tax. The only thing you have to be careful with is mounting the cpu to the motherboard. Just make sure you put it on the correct way or you will bend pins and be hosed. If you're worried about doing that part yourself pretty sure micro and frys will mount for free if you buy from them. It isn't difficult by any means you just have to pay attention.
