So you're saying I should go for the better GPU? I game more than I video edit. Is a better GPU advised for gaming or a better CPU?
Most games require good GPU, and a good-enough CPU. The 8320+7970 will be better than 3570k+7950. You're better gaming by getting the 7970 over the 7950, and you're better for editing in getting the Fx-8320 over the 3570k. Win-win.
