Interesting points. I would buy 4790K and overclock it if I wouldn’t need 64 GB of RAM. That’s why I see that 5820K with overclocking (+Asus X99 A 2 motherboard) would be my best choice. 2 x Xeon processors + proper motherboard are just too expensive but maybe in the future.
I found this article and I’m interested to hear what do you think:
"I know a lot about this stuff, besides being a soon-to-be IT major, I built a water-cooled rig 4~ years ago I just decommissioned for a Micro ATX. I’ve broken overclock records on a few old AMD chips as well. My advice on the 4770k vs the 5820k… first of all, take a look at this benchmark comparison…
I highly recommend anandtech for any computer parts comparisons because they offer full and unbiased benchmarks for hardware vs. hardware showdowns. Looking at that comparison, the 5820k doesn’t exactly blow away the 4770k by any means. In fact, in some spots it shockingly lags behind. In several of the benchmarks for gaming, which are hugely single-core dependent, your current CPU performed better than the 5820k. Also, a big one; look at the Cinebench R10 singlethread comparison; your 4770k had a better single-core bench than the 5820k, and by a lot. As others here have said, certain aspects of the music development are mostly single-core dependent and NOT mutlicore, you you would essentially be wasting $1,000+ on LESS performance increase.
Furthermore, look on their benchmark for the some of i7 extremes, like the 5960x. That is a $1,000+ CPU that your current CPU outperforms in some single-threaded applications, and is neck-in-neck with others. I am saying all this to discourage you from wasting all this hard-earned cash. I see so many people waste money on insane PC rigs and the performance increases are minuscule at best. The truth is, you have a GREAT CPU, the 4770k is still a very solid, very modern CPU. Not just with music, but in general, you’re not going to see THAT significant of a performance increase. The numbers don’t lie.
You have two routes here; overclock, or go with a server CPU like Intel Xenon. BUT… even with a Xenon, those are CPU’s heavily focused on multi-core processing, although their single core performance IS better. But again, the gains are negligible. Icenburg has the right idea, a 2 xenon core. But again, you are spending a lot of money, and for what? Some bumps in performance? I don’t think that’s going to solve your problem. Someone above said it; have big enough of a project, and any computer you throw at it is going to struggle. My advice is to tone it down on the projects. Once you have the instruments and melodies totally figured out, record them as audio clips. At the very least, this can make mixing much easier. Big enough, studio-quality orchestra tracks don’t necessarily get created on DAW’s but in hardware-based mixers that are recorded as audio and later sent into DAW’s."
