hey ;)

►Question
so I want to upgrade from my old fx-8120 to a 4790k/5820k.

I mostly play games, but due to my youtube hobby I spent just as much time editing and rendering videos. I also love creating logos, backgrounds, ovelays etc.

I mainly use AFTER EFFECTS, SONY VEGAS, Photoshop, Illustrator, Indesign and Premiere Pro.


►My current system is:

AMD FX8120 Zambezi 3,1GHz OC to 4.0 Bulldozer
Corsair H60
Kingston 8GB DDR3 RAM
MSI GTX 970 Gaming 4G Twin Frozr V
Samsung 840 SSD 250GB (OS/programs)
Western Digital 500GB (programs/storage)
Seagate Barracuda 1000GB (storage)
Seagate Barracuda 3000GB (storage)
Gigabyte GA-970A-UD3
Corsair CX 600W
Shinobi XL
Windows 8.1 64-bit



►So:

I know I will need a new mobo+ 16gb ram as well
- and I know the 5820k version is a lot more expensive

I just want to know how much of an improvement will I get from 5820k over a 4790k and is it worth?

PS: I plan on buying another gtx 970 sometime next year
 
Solution
DDR4 is very expensive, but at the end of the day you get what you pay for. The 4790k is a very good cpu, and I would personally choose that over the 5820k due to the massive increase in price for not so much noticeable performance gain.

Once again, it just depends on whether you want the best of the best and are willing to pay the price for it.

AE / Vegas etc. will run perfectly on the 4970k, but of course the 5820k will be faster due to faster ram, 6 cores etc.

Tl;dr - The more you pay, the better performance you get but at the end of the day the 4790k will give more bang for buck and it will be a cpu you wont be disappointed with.

I would say definitely worth it if you do video editing. You will get almost 50% more rendering power out of the box. Other reasons would be if you plan a big multi gpu set up, but with a single 970 it would make no difference

Just in case you did not know it, you would have to buy the new CPU, a brand new X99 motherboard, and brand new DDR4 memory. You cannot use the new cpu with older boards and older DDR3 memory. Right now you can expect to pay $1,000.00 or more for those three components.

I read numerous technical reviews comparing the Intel Core i7 4790K with the new cpus. The 4790K is a definitely better value and it costs a lot less.
 

The price difference between the Core i7-4790K and Core i7-5820K is pretty small. $300 vs. $375. If you ignore platform costs, that would make the 5820K better value for multithreaded usage. But the DDR4 memory and X99 motherboard does indeed add to the cost. If we take a basic X99 motherboard vs. a basic SLI-capable Z97 motherboard, and 4x4GB DDR4 vs. 2x4GB DDR3 (added to presumably 2x4GB), then the price difference is just under $300:

Yes, the difference between the two CPUs is not at all that much, but when you factor in the new mobo + RAM you have to get with it, the price difference becomes huge as you've illustrated.

It comes down to what I said above. Does OP value the extra threads and processing power which is essentially overkill for his needs in order to have the 'best of the best'? I think you would be better off going for the 4790k as you save money and you also need to consider that the 4790k is very good at what you want to do. I think that you wont notice too much real world difference between the two platforms.
 

The 4790K has very high stock clocks, but very little overclocking headroom. The 5820K has lower stock clocks and more overclocking headroom, which means it will catch up once you overclock. Those benchmarks are run at stock clocks, skewing the picture in favor of the 4790K. It also contains a lot of single-threaded benchmarks, whereas the multithreaded performance is what's really at issue here. And the 5820K crushes the 4790K in most of the multithreaded benchmarks, even with the disadvantage of lower clocks.
