Dual 2011 vs dual 1366 setup: video rendering

[mrjayviper]

I have a dual 2011 (2650L V1. 8 [email protected]) on its way. I got the setup for around $400 be including 64GB RAM.

but I have an opportunity to buy a dual 1366 setup (E5645 6 [email protected]) for less $100. This includes 48GB RAM.

Is there a significant performance advantage of the 2011 setup? I know that the newer CPU has AVX which might help.

I've looked at comparisons but nothing really specific to video rendering. Thanks
