Is It worth upgrading i7 950 @ 4.2ghz to a i7 4770k?

I'm running a I7 950 @ 4.2 ghz.
Rest of specs in sig. 6990 is now a 7990.
I was thinking of upgrading to a i7-4770K and oc'ing it.
I mainly play BF3 / BF4.
Is it worth it?

I'm getting 98% load on all cpu cores in BF4.
All settings are Utra.
Is that good or bad??

4770k oc'd would reduce the bottleneck a bit but it would be a pretty costly upgrade.

So....
Worth it or not?

On BF4 I'm getting around 98% cpu usage and between 80% & 100% on gpu usage.
On BF3 it's 90% cpu usage and between 55% and 100% gpu usage
