get a mac(multimedia)... and because you are a student... use a console for gaming.
for editing... it is the program that you are using thats more important, and because you are a student the time to encode is secondary...
and since you are a student, money is tight... so intel is quieter, less power consumption, but more expensive.
i am useing an AMD 8350, only because that is the "eco-system" that i have.
go the cheapest intel you can find... h61,2120,gtx 660....
