My setup for PC gaming channel is the following:
Macbook Pro - I7
Recording Equipment - TurtleBeach PX22 and a Blue Snowball iCE Mic
Software Editing Equipment - Sony Vegas Pro 12 and Adobe Master Collection CS 6 (Both obtained through school sources)
This for me works really well, my problem is getting my videos noticed! Lol.
That will set you apart from the rest of the herd, is to get your video noticed and take it off the ground. I had one video that actually made it pasted 1k views, so I am really happy about that, and the other videos were like around 500+.
