Looking for advice on build (inc. where will bottlenecking occur and will it be substantial)

[tmshe2]

Hey guys doing my first PC build soon, Im going to be using it primarily for gaming with only quite light CAD (mainly using solidworks and potentially a bit of ANSYS).

At this stage my budget for the computer (without peripherals as a monitor will be purchased later at around a WQHD quality with at least a 144hz refresh rate) is around $2800 AUD

and my current build is looking to be the following:

CPU: intel i7 8700

CPU cooler: Noctua d15 

Motherboard: Gigabyte z370 AORUS G5

RAM: Kkingston  2x8GB 2400MHZ DDR4 Hyper x Fury

Primary storage: 500GB Samsung EVO 960 M.2

Sec. storage: 2TB Seagate Barracuda 64mb cache 3.5"

PSU: 750W corsair RM750i

GPU: gigabyte GTX 1080 Tyrbo OC 8GB 

Tower: Aerocool xpredator case full tower

OS: windows 10 home

 

I later realised that with what i'd be doing most of the time that hyperthreading may not be that useful and the as such was thinking if it would be more beneficial to get and i58400 CPU instead

and use the savings to get a Gigabyte GeForce GTX 1080 Ti OC 11GB Gaming Graphics Card (the pricing works out to be the same in the end)

 

So overall, which build would you reccomend and would bottlenecking be a serious issue with either of the builds, thanks

i7 with 1080

If you're getting a locked CPU, don't bother with a high end board and an NH-D15. 

For gaming, an NVMe SSD won't help with anything. Not Windows boot times, nor with game load times. Just get a decent SATA SSD.

750W is way overkill. 550-650W is already plenty for an overclocked system.

Get faster RAM. >2800 MHz.

For gaming, an 8400 shouldn't have issues keeping up with a 1080 Ti at 1440p.

I choose that board because it comes with built in WIFI (which unfortunately from what i found required me to go a few tiers up in boards) are there any other z370 boards that have built in WIFI at a lower cost? and does it matter that the CPU recommends no higher than 2666 MHZ for memory? cheers

From PCPP, there are a couple of cheaper boards. You could also just add a WiFi card. 

You might as well ignore Intel's RAM speed for CPUs. Getting a higher speed kit will just improve the performance. It will technically be overclocking, as it's not 2133 MHz 1,2V, but absolutely nothing to worry about.

Select at least DDR4-2666MHz memory, that is the maximum non overclocked speed of the Coffee Lake cpu. Faster memory can help in many games, but generally it's only 1-2 fps, hardly worth paying a premium.

 

A locked cpu like the i7-8700 will not really benefit from an NH-D15. You might look at something like the Cryorig H7. Even that is more cooler than really needs. The cpu is only 65W TDP.

 

I would consider a different case. It strikes me that the fins at the top of the XPreditor will be prone to breaking.

Thanks!, I have actually changed my build slightly, I've decided to go with a Zotac Geforce GTX 1080 Amp Extreme instead but wanted to check if it would fit in the given case with the NH-D15 (as both are extremely large products and I would prefer to have the 1080 in the faster PCIe slot)

If you are getting a locked cpu (non-K) there is little point in getting a large cooler like the NH-D15. In fact I would characterize it as a waste of money. Something like the H7 or NH-U12S will provide more than sufficient quiet cooling power.
