I am currently collecting money to build a pc and once it is done, I intend to be recording and uploading videos to youtube (as well as do some heavy gaming). As such, I was wondering which CPU was best for this (I heard this is one of the few scenarios where I should get an fx 8350 over an i5/i7 due to extra cores but I want a second opinion). Also, since I will be doing some video editing, would it be worth getting a decent sound card too?
As a side note, I play lots of different games, and some of the older ones will inevitably benefit from an i5 over an fx. If I did get an fx, what sort of fps differences would I get (eg games such as total war series, dawn of war series, mount and blade series, basically anything that has a low thread count).
My budget is ~£200 so I can get something like an i7 4770k if you really think it's worth it. I can also stretch this budget if it is worth it.
