Hello guys
I just started building my new rig, primarily for video editing and gaming.
I did a heavy search on processor
4820k vs 4770k and stuff
I encountered a memory bandwidth article.
It said 32GB RAM might get bottlenecked on 4770k as it has only 25.6gb/s bandwidth whereas 4820k has higher and it wouldn't.

Is this true? Which processor would you recommend though?

Won't recommend 4820k, unless you really need a 2011 motherboard.
4770k have new architecture performance by a bit over a ivy-bridge.

That is correct. But I didn't really get the answer I needed. Memory bandwidth and how does it effect ram and gpu?

And that best solution thing was a mistake with this non mobile friendly website. You still got it though :-P

It is the maximum speed the CPU can read/write from the memory.
I can't imagine it having a greater impact.

So could 32Gb 1866Mhz CAS 9 RAM bottleneck it?
Or could gtx 780ti at its full potential?
