Searching for a nice PC setup for UE4

Hello all!

Not sure where publish that, well:

I’m thinking of change most of my hardware soon because it’s a little old and although in the past I could handle Unreal without major problems, now the issues are coming. I want to choose a nice economic pc. Not searching for a beast, just something that can run multiple instances and compile decently UE4, so I was thinking on these main components:

  • Intel Core I5-8600K 3.6GHz
  • Gigabyte GA-B360M DS3H
  • 2x8GB of RAM DDR4 at 2400 MHz
  • Corsair RM 750X V2 80 Plus Gold Modular (750W)

I’ve been reading and some people say that this CPU is ok for gaming, but it would be more recommended buy and I7 to things like game development and rendering. The main problem is that the 8º generation CPUs are so much expensive right now, and I just want to know if an I5 would be ok for run UE4. I’ve been thinking also on change to a higher CPU in a future and buy a 1080 GPU.

So, what do you think? Thank you.

You could look into 7th gen i7 cpus for a good deal.

You could consider getting a LGA 2066 Core i7-7800X which costs almost the same as the i5-8600K. But with that you would have Quad-Channel DDR4 support on a X299 motherboard which obviously would be more expensive indeed but it is well worth the money. Gigabyte X299 UD4 Pro or ASUS TUF X299 Mark 2 maybe. 32GB DDR4 RAM would be better for UE4 development. And you could get a Nvidia GTX 1060 GPU which is not very expensive and is good enough to work with UE4 (obviously a GTX 1070 or a RTX 2070 would be better but way more expensive too)

Several game development tasks can utilize multi threading:
compiling shaders (this is cpu not gpu)
packaging (this takes forever)
building lights
compiling code - engine and game

An i7 is better than i5 for these tasks.

how much better depends on game - how much code, how big level, how many assets.

fast i5 will work - but this is one of the few tasks that takes advantage of multiple cores well.

ultimately - how much is your time worth?

You should consider buying an i7 instead of a i5 as it will perform better compiling C++ and building lighting.

Depends on your use case really. Do you only fiddle around in UE4 or spend major time in it? i5 is perfectly fine for gaming but way worse for UE4. You really want the extra cores of the i7. Even a 7th generation i7 would probably be quite a bit faster than a 8th generation i5.

I would actually consider the i7-4790k as the processor, and upping memory to 32GB if possible.

I would actually downgrade the PSU from 750W to 650W. I have an i7 8700K, 16GB DDR4, Palit GTX 1080 Super Jetstream, 3 HDDs, 1SSD and 4 extra 120mm fans and it all runs on a Be Quiet Straight Power CM11 650W 80+ Gold.

Is it worth any value going up to 64 GB or 128 GB of DDR4 and would be better on speed with DDR4 3000, 3200, 3466, 3600, 4000, 4200, 4400, 4500, 4600 MHz?

I have 32GB and I can comfortably open multiple visual studio instances and run the editor. Typical usage goes nowhere near 32GB more than that would just be a waste unless you have a specific use case for it.

For DDR4 speeds as far as I am concerned it is just a marketing gimmick with no actual value. Pick the lowest price ram from a reliable source regardless of speed.

Also the speed is maintained by the UEFI depending on the max default ram speed tested with the CPU. On my PC its 2666mhz even though the RAM itself can clock at 3000mhz.
My research has shown that RAM speed barely matters. It can provide a small boost but usually the price is not worth it. Just go with 3000 or 3200mhz depending on the price.

There is LPX and RPG in corsair vengeance or is corsair dominator platinum better, 8 or 16 GB stick

I was wondering is TR4 AMD threadripper compatible with unreal engine 4, i know that i9 9900K, 7900X, 7920, 7980xe are where i discovered on Pudget system requirements for Unreal engine 4 workstation configuration, i got many system configurations on pcpartpicker, for system compatibility, i came up with 2 systems for me to decide hear they are
system 1
1 x i9 9900K
1 x MSI Meg godlike motherboard
1 x Asus Rog Ryujin 360 121.8 CFM Liquid CPU cooler
4 x Corsair vengeance LPX 64 GB (4 x 16 GB) DDR4 - 4000
4 x Samsung - 860 Pro 4TB 2.5" SSD
1 x Nvidia RTX 2080Ti GPU

2nd Choice
AMD TR4 2950x 16 core CPU
Gigabyte - X399 Designare motherboard
8 x Corsair dominator platinum 128 GB DDR4 3466
4 Samsung 970 Pro 4 TB M.2 - 2280 4 x 1TB SSD
1 x RTX 2080Ti GPU
So thats it deciding which one
