AMD Phenom II 965 BE vs i5 3470

Is the i5 really worth the $100 difference? Al I'll be doing is gaming with my radeon 7870, maybe convert video files, and render a lot of videos on Sony Vegas 11.

i5 defenitely! for rendering it will shit all over that AMD cpu 

you want 3570k.

for rendering there will be a big difference, the FX-6300 or FX-8350 is more comparable to the i5

depending on what game though, there wont be much difference between any of them

AMD is better for the money, but if you got the money for the i5, go for the i5

Look around. I picked up an i5 3570k for about $20 less than the 3470. There are good sales here and there. 

I suggest the 8350 if you use sony vegas often.
