I use my PC for video editing, 3D rendering and music production.
I don't want to 'break the bank' so I'm not sure what to do. I know the 4770k outperforms the 980x however, it would require me to get a new mobo, RAM and cooler.
I can grab a 980x for £300.
Otherwise, the 4770k, I can get for £250. I'm still undecided on the mobo for it but I'm looking at going with either the Asus Maximus VI Hero or the Asus Sabertooth z87....both are around £150.
So, it's probably going to be double the price of a 980x upgrade.
Well its abit depending, offcourse the 980X is a 6 core 12 threads cpu, so you would notice a significant performance boost in editing and rendering, if your software is capable of utilizing more core´s and threads. haswell is offcourse faster core for core, but still, the 980x can do more threads at the same time.
In the end in my opinnion, its just about how satisfied you currently are about your performance, in my opinnion, if you not get bottlenecked and you satisfied with the current performance, i would personaly not botter to upgrade now, in my opinnion. i expect that next year broadwell will be launched, and maybe also Haswell-E.
i personaly expect alot of haswell-e for pro editors and renderers, 6 and 8 core cpu´s
xeons are higher binned for voltage and freq, I got my x5560 to 4Ghz with plenty of voltage headroom, only thing stopping me is I need a better cooler, I'm getting one of those next paycheck 2 weeks from now, then a xcps water cooling kit
If this is any indication of CPU power... LINK go with the 4770k
However as you are rendering, you can be quite memory heavy, to which if you have the 930 loaded with 6x 4GB modules, if you carry this to the 4770K you will only have 16GB without buying new 8GB DIMM RAM modules. Which may hinder you overall.
