Hello

I am ready to buy a new pc, I have money put a side.

I want to get what I can for the money.

I will use the computer for gaming, 3D design/rendering, Graphic design, video editing, and music production.

Will the i75820K with the DDR4 ram be worth it? Or will the i7 4790K be better and more price sense?

Buying the i7 5820K will push my funds higher than I want to speed but if that extra 200 dollars(extra for the mother board and cpu) is worth it I will go for it.

If not I will stick with the i7 4790K.

Yeah for your usage, the 6 core 5820k would be worth it.

It depends, remember the 5820K will bring a new platform with it. This means along with higher upfront costs there may be bugs in the first couple batches, furthermore from the prices floating around the internet DDR4 prices are about a 70% advantage for equivalent speed memory. Therefore if we assume you'll be buying at least 32gb memory and we take a standard price of $350 adding 70% will be an additional $245 plus the $200 you're already adding for the cpu and mobo. That means you're down ~$450 and it's up to you to justify the price difference.

It may be better just to go with the 4790K, There will be advantages just from the DDR4 alone if you go with the i7 5820k. One thing to note about the i7 5820k is that the PCI-E bandwidth is not as great as the other Haswell-E Processors. so 28 lanes opposed to the usual 40 fro previous gen Socket-R SKUs. Also when you get the i7 5820k that is the lowest binned processor in the Haswell-E 2011-3. opposed to the highest Binned lga 1150 i7 4790k. I know I not give a good solution, though one can't help but wonder. I would opt for the i7 5930K if your going to get the X99 platfrom. Everything is going to cost so much anyway so get the best you can.

Unless you don't care on spending an additional 1000$, the I7 4790k is definitely in a better spot. Sure, the extra performance is going to be considerable, but then you should just go with the 5930k or better yet the 8 core 5960x.

As for gaming, the 4790k will probably outperform the 5xx0k/x, due to it's higher clock rate. For rendering, the haswell-e's will outperform the devils canyon.

According to this review, the 5820k is usually the fastest cup when gaming.

http://www.tomshardware.com/reviews/intel-core-i7-5960x...

I'm not sure it's entirely accurate seeing as it beats the 5830k which is clocked .2ghz higher, and has more PCI lanes.

In other applications, it easily beats the 4790k. However, equivalent parts to ddr3 are more expensive, so it's up to you. If you have the extra $, go 5820k. Otherwise, the 4790k is still great.

Thats just natural variance. 5930k, 5820k and 4790k will do pretty much exactly the same in games, because they are limited by the gpu. If they were not, the 4790k would probably win, just because games don't utilize more than 4 cores and the 4790k wins in single thread performance due to it's high base clock.
In other applications the haswell e's obviously dominate if 16 threads are used. Also in memory intensive appkications due to more lanes and DDR4. But even then, considering most programs do not use more than 8 threads, investing an extra of $500 wouldn't be very smart unless you're swimming in money.

For gaming there is almost no difference right now but for actual work more cores equal faster so if you are doing a lot of work its worth it if not then no.

Makes sense to go for Haswell-E IMO for his other productivity needs, where it really out performs DC, plus this will be a beast of a gaming cpu for years, the longevity should be huge.

Meanwhile already $200 exceeds his budget and he's going to pay at least $500 more for that upgrade.

Where is the extra 500 dollar cost going to come from?

Motherboard and ram. And of course little more cpu cost.

However, buying DDR4 now, even though it's overpriced, saves him money versus buying DDR3 now and buying DDR4 when he upgrades in a few years. Same with buying a z97 mobo and having to upgrade later, where x99 is guaranteed at least broad well, and probably more.

The bottom line is that going 5820k will save you money in the long run, and give you a better CPU, but it's up to you whether you want to spend the extra money.

z97 will support 14nm 5th gen.
x99 is not guaranteed to support any more than one more generation. For $500 he can upgrade to the next gen no problem. Or with $800 to come out with the same cost as an upgrade from the 5820k.
So unless he's upgrading each and every generation, the 4790k will come out cheaper afterall.

Which is the one generation I mentioned. There is no other generation after broadwell that x99 is guaranteed to be compatible with.

Broadwell has a short life span as skylake is a year behind it, and skylake will be socket 1151.

And skylake will have a short life span because cannonlake is just around the door?

Thats not true at all, lifespan for those cpus can be expected to be 8 years at least, unless used incerrectly.

I think you misunderstand what he means by life span. I dont think he means how long the cpu will function for, I think he means how long the cpu will be on sale for, before being replaced.

I know what he meant (as I understood, the cpu being top of the line, aka newest out). However, that's not what the life span is. And therefore quite irrelevant because intel always releases new architectures or die shrinks in short pattern.

Ah ok, you are just being pedantic then.
