RTX 3080 & Intel Core i9 Gaming PC Build Guide

We've got the latest 11th generation Intel CPUs in the studio, and we're going to put them through their paces in a series of builds! First up, an i9 11900K & RTX 3080 system build!

Intel’s latest 11th generation CPUs have landed, and arrive at a time when AMDs dominance has never been greater.

When AMD first re entered the CPU space competitively, with Ryzen, there was always a bit of a caveat to be had. Multi-threaded performance was good, but single threaded metrics (crucial for most gaming titles), had a tendency to lag behind. With Ryzen 5000 AMD truly took the single and multi threaded crown – Intel’s 11th gen chips are their direct response.

So much so in fact, that Intel have reduced the core count on 11th gen, compared to the 10 series chips, in a bid to push clock speeds and single threaded number further.

This move is not one Intel would have wanted to make, as it essentially surrenders the multi-threaded crown to AMD… but necessity and all of that?

In order to evaluate the performance of 11th gen, we’ve done what we do best: put together a full build guide! This system centres around the range-topping i9 11900K, an 8 core, 16 thread CPU with a single boost clock speed of up to 5.3GHz.

The Parts

CPU: Intel Core i9 11900K

This chip is one of the most powerful on the market, and while it still get beaten out by AMD’s competition Ryzen 5000 chips, Intel may have one or two tricks up their sleeve.

Rumour is, that Intel stock allocations may actually be pretty good – something which goes against the trend of the PC market in 2021. Stock is much more of a variable than it ever has been before, in a market where GPU shortages have extended into power supply’s and CPUs.

GPU: Cooler Master ML360R

With a 125W TDP, the Core i9 11900K is a powerful chip that needs some good cooling to ensure it can reach the upper limits of its boost clock speeds. In our recent video, here, we demonstrated the importance of good cooling for clock speed.

This Cooler Master ML360R fits the bill perfectly, a 360mm radiator, addressable RGB fans and long enough tubes for our large case choice make it an awesome option!

GPU: Asus TUF NVIDIA GeForce 3080

In terms of the GPU, our choice has to be an RTX 3080. While recent AMD releases in the form of the 6800 and 6800XT are compelling options, stock on those seems non existent. The 3080 isn’t loads better, but we are seeing more examples around. We also believe the 3080 to be the best card on balance, on the market right now. Stay away from the 3090 and 6900XT if you’re a gaming-only user (as the value is just not really there), is our advice!

RAM: Corsair Vengeance RGB Pro SL 32GB

One of the latest product releases from Corsair, the Vengeance RGB Pro SL is an awesome choice – RGB, reliable, affordable and it looks great! The Corsair iCUE customisation is also top class. You can definitely go for something a little more flashy, but we think this Corsair kit fits the bill perfectly!

SSD/Storage: Western Digital SN850 1TB

Storage is actually one of the major selling points when it comes to 11th Gen Intel CPUs. With widespread support for Gen 4 NVMe SSDs, across both the range-topping Z590 and more affordable B560 chipsets, fast storage has reached the masses.

In our speedtests, this drive got close to the advertised 7000MB/s read and write speeds, and it comes in at a price point that isn’t too eye watering!

Keep scrolling for the rest of the components, but remember: we’ve uploaded a video version of this build below!

Motherboard: ASUS Maximus XIII Hero

When talking about our motherboard choice for today’s build, we will admit that we might have gone a little overkill. This is the ASUS Maximus XIII Hero board, which is one of the most expensive Z590 boards out there. It does have a monster feature set, which helps to justify the price – which includes plenty of overclocking supports, for the enthusiasts out there!

Case: Corsair 5000D Airflow Black

Picking a chassis for a high end build is always a choice which varies on a user by user basis. The Corsair 5000D airflow is a little boring out of the box, which is very much the point.

Use this chassis as a base to water-cool to your hearts content and add radiators, RGB fans and more to get this case exactly how you like it. Build quality is top notch, and all things considered the RRP isn’t actually too bad!

PSU: MSI A850GF Fully Modular 80+ Gold

The last component of this system is the power supply choice – we’ve gone a little left field, and used a unit from MSI of all people! MSIs expansion into a wider range of components, outside the GPU and motherboard spheres, has been impressive to say the least! This fully modular, 850W power supply is no exception.

It’s quiet, efficient, affordable and comes in a pretty compact form factor. Happy days!
