Hi Guys

I haven't built a PC in a long time, and the last time I did, I made a big mistake that resulted in a CPU and GPU bottleneck, as well as some compatibility issues. I'm looking at the setup below and would like to know if it's a good high-end setup or if you would recommend swapping out parts that are overkill or might introduce bottlenecks, etc. Any advice would be greatly appreciated. I have already purchased the monitor which is a Samsung Neo G9 that will be running at 5,120 x 1,440. Want to take my time with the PC build to make sure I do it right this time.

Hey, bud

Off the top of my head reading this quickly.

Get 3600mhz memory. Ryzen doesn't get much benefit for anything faster than that.
Use the money saved to get a better board.
B550 Gaming E Wifi or an X570 board.
Make sure the NVME is Gen4 for the best speeds on that build.

Wait for next gen.

I don't mind swapping out the GPU for a later model when it comes out, or do you suspect that the newer GPUs will use PCIE 5 or have any other more stringent requirements?

I'm looking for reasons to avoid waiting too long LOL

If you're building new now, it's more worth waiting to see what 7000 series pricing is and performance on mobo's, it'll knock current gen pricing down somewhat as well (hopefully) and pcie gen 5.0 on the platform will just be better. It'll tick over that longevity more than current gen as it's a mix, where as this'll be the first gen with gen5.0 across the board, can't see going wrong with that overall.

i.e. it's more worth your time to wait and see what next gen is a& has to offer than splurge now and possibly be in the market for it. It's close enough to wait it out, even if it only releases early next year. Patience pays off well most of the time.

This exact reason I am holding onto my PC and wait to see what will happen next year.
 
DDR5 along with PCIE Gen 5 is still in it's infancy. I would wait quite a while for these to mature before adopting any of these technologies. Not only will you pay the "early adopter tax", but graphics cards don't even saturate PCI Gen3 yet, never mind Gen 4 or 5. Only NVME SSD's would take full advantage of PCIE Gen 5, and even then you would not notice it in gaming/day to day use. So not much to gain there. As for gaming performance, DDR5 will not gain you any significant advantage that you will be able to spot with the naked eye. My understanding is that currently it's less than 1% increase and yet it costs a fortune. As for AMD 7000 series, I would wait as well.. I love my AMD, but I also know that when it comes to AMD you set yourself up for frustration as waiting for a mature BIOS release is the best option.
 
How tech savvy are you? You ready to troubleshoot DDR5 and a brand new AMD Platform?

If you want a PC now, get a PC now but be aware that things are going to change in the future and you're no longer going to be on an absolute top spec computer and something that'll match your build will come in at cheaper. That being said, what are you going to use it for?

Additionally disregarding all of the issues with waiting vs buying now. Your build is okay... definitely consider a different motherboard depending on purpose or any specific set of requirements of the PC will be able to advise. Then that CPU cooler man... its decent for budget builds but not appropriate for something of this class.

I humbly disagree with this
I think it's close to a 10% difference which will be noticable.
Is 10% worth 100% increase in cost, fudge no. To me anyway.

I haven't tested it myself. I'm just gauging by the sources I've consulted.
But yea, I do agree that DDR5 is horribly expensive for any perceived gains.

Hardware Unboxed recently tested the new Spider-Man remastered on various CPUs. They also compared the 12900K on DDR4 vs. DDR5, specifically with Ray Tracing enabled. At 1080p and 1440p, switching the 12900K to DDR5 massively increased the FPS:

Granted, this is a fairly niche scenario, but I think it's a sign of things to come on DDR5. I think I'd wait for the new platforms too at this point, especially if you are building a brand new system from scratch.
 
Wait a bit and see what the markets do with the ETH merger. Also, this build will probably be overkill for most things. I agree with grabbing a better board, no use running all that pretty gear on a budget(ish) board.

Well there you have it. But like I said, DDR5 needs to mature a bit more to justify spending that much on it.

DDR5 really isn't that expensive locally. Costs more than cheap DDR4 but isn't far off of the price of expensive DDR4.
 
Phoen1x said:
Geesh. Looking at that, if I had to upgrade my G.Skill DDR4 to DDR5 it would literally cost me double the price.

Wait you do photography and editing... don't you? i.e your opinion on the cost of equipment doesn't matter because you are semi forced into all of the specs.

You have a point. I will just be over here in the corner crying. WHY??? Why am I forced into the top 1 % of PC specs. Oh life has dealt me a cruel hand...

DDR5 is great. Rules:

1. Buy a Hynix kit. The Kingston 6000C40 is dirt cheap on the Kingston Takealot store.
2. Get a RAM fan.
3. Don't buy Asus.
4. Don't buy Gigabyte.

There, that's all you need to know.

Take it from someone who knows the pain and pleasure of DDR5 :cool:
Edit : That's him not me !
 
Most of the kinks we dealt with will be ironed our with Raptor Lake and Zen 4 . The caveat is that ironing out those kinks could only be achieved through extra R&D, brute forcing more PCB layers, and having tighter QC tolerances with regards to the final PCB cut out. Do not expect X670E and Z790 boards to be cheap. Don't expect it at all. And further than that, do not ever expect D5-7000 out of anything in the R5000 range. It's just not going to happen. Maybe one day.
 
Another thing to note:
No one has really stressed this, but you're going to need to pay special attention to case selection and your cooling strategy for your CPU. The 12700K, 12900K, 5900X and 5950X are all incredibly hard to cool under heavy AVX tasks. Don't expect to buy anything other than a good 360 or a 420.

You're also going to have to worry about the vendor with this because certain mounting mechanisms lead to worse contact for both thermals, and in some regards, contact with the VDD socket pins.

AMD likely went with LGA because of DDR5 and not for any other reason. Dude to the high data rates, DDR5 requires very fine-tuned mounting pressure and you can literally break training/stability with varying amounts of it.

The uncore and memory I/O portions of Alder Lake are also incredibly sensitive to heat so running your chip at 95c under a heavy workload could very possibly cause data channel instability where there previously wasn't any. This is a separate issue to re-train instability.

Zen 3 was already heat sensitive in terms of FCLK and UCLK, so I don't expect Zen 4 to be any better at all.
 
To round it off with a basic guide:
  • Buying 13900K/7950X - 420mm
  • Buying 13700K/7900X - 360mm
  • Buying 13600K/7800X - 280mm

I want DDR5-7000 to be daily'able:
  • Wait for Hynix A-die kits ~ R7000-7500 for 2x16 when readily available
  • Motherboard with no fewer than 10 PCB layers
  • EVGA, MSI, or ASRock
  • Active cooling, regardless of voltage, there's a power supply chip on the RAM stick and even if vendors start putting thermal pads on them, you'd need hectic case airflow to get away with it
OR:
  • Get a good board
  • Purchase a R5000-6000 Hynix M-die kit
  • Learn to manually tune
