Recommend me a Graphics Card

I've had time after work to look this thread over.
With the power supply I have in the box 600W I should be able to power the r9 270x which you said requires 550W. I read a review that said the fan started to fail after a few months though :/

It should be more than enough for AC right? To run recording software while playing?

Is it possible to upgrade the CPU to a quad core in the future? I didn't know you could just change them like that. (Again, not very educated in this)

Your mobo socket don't support the newer i-series processors, you will have to upgrade the mobo too..
