Skytech Gaming’s Azure 2 is a no-compromise prebuilt that delivers top-of-the-line performance. We’ve recommended Skytech Gaming prebuilts previously, as they provide the best value for money. The Skytech Gaming Azure 2 is expensive but has flagship components from Intel and NVIDIA. Combine that with excellent cable management and virtually zero bloatware, and you have a prebuilt that’s an easy recommendation. 

Inside the Azure 2, you’ll find an Intel Core i9 13900K processor mounted on a Z790 motherboard. Consumers can also leverage the insanely powerful RTX 4090 graphics card from NVIDIA, a titan of the modern age. This GPU works incredibly well alongside the hefty 64GB of DDR5 RAM, making this system perfect for tackling top-end games at max settings, or more complex and harsh workstation tasks. The higher RAM and VRAM capacity in this system make the Skytech Gaming Azure 2 a capable rendering machine.

The NVIDIA RTX 4090 is a chunky GPU, it’s bigger than a regular brick. While the case used in the prebuilt has ample space, the 4090 might still prove big for it. The huge size may restrict airflow for the air-cooled GPU. 

The Azure 2 comes with 6 fans to help keep the temperature down and performance up. The fans tend to get a little loud under a consistent load. However, there is no thermal throttling, so it is a small trade off overall.

While Z790 motherboards are only marginally better than the older Z690 chipset, it would’ve been better. Especially considering the high price of this prebuilt. 

The NVIDIA RTX 4090 is already a huge card. Stuffing it inside an ATX mid-tower chassis is not ideal. While it does save space and makes the machine look great, the airflow might get impacted.

There’s a USB Type-C port on the top of the case. However, it’s closed with an unsightly rubber stopper. The “port” inside doesn’t work as it isn’t connected to the board. You’ll need to order the cable from Lian Li to get it working.

This iBuyPower prebuilt comes in an all-black chassis with heavy glass windows on both sides. Unfortunately, the motherboard has a white colour scheme and design elements, that clash with the aesthetic.

The Vibox X-202 is a beautiful machine. The aquarium-like case has glass wrapping around two sides without any divider or support. This gives the prebuilt a unique look. The insides are equally impressive, with a top-of-the-line Intel Core i9 13900KF processor that pairs very nicely with the RTX 4090. The components are illuminated by RGB lights from the fans, tying the whole setup together beautifully. 

The Intel Core i9 13900KF processor lacks integrated graphics but that’s fine, the Vibox X-202 already has a beastly dedicated GPU. The processor runs slightly cooler than its standard counterpart, the i9 13900K. This gives room for overclocking down the road. The Vibox X-202 is one of the best white prebuilts, however, the black GPU stops it from being the perfect all-white machine. The only downside is the smaller CPU 240mm cooler installed, as the processor already runs hot and it needs all the help it can get.

The system uses older DDR4 RAM. Vibox should’ve opted for DDR5 RAM, in order to ensure that this system provides optimal performance, and will stand the test of time. It’s a cost-saving move on an expensive prebuilt.

The Vibox X-202 comes with a Vibox Infinity ARGB 240mm. It’s adequate for weaker CPUs, but given the high price of the prebuilt, a 360mm cooling system would be better.

Are Prebuilts Upgradeable?

Yes! Prebuilts can be upgraded like regular PCs. Most prebuilts use readily available off-the-shelf parts, so swapping is just as easy. The only restrictions would be the cost and compatibility. 

Change the fans, swap the storage, upgrade the PSU, insert more RAM, or even replace the whole motherboard down the road. Keep component compatibility in mind when swapping parts though. An AMD processor can’t be installed in a motherboard made for Intel CPUs. Similarly, some motherboards won’t support faster RAM, so upgrading memory would be useless.

The biggest advantage of a prebuilt is cost saving. If you are planning to buy a prebuilt and immediately start swapping parts, this is going to get expensive. Upgrading a prebuilt after a while is not only feasible, but will save money as only essential upgrades are needed.

How Much RAM Should a Prebuilt Include?

While 32GB of RAM is often enough for modern gaming it doesn’t cut the mustard in every singe title or use case, and certainly not when gaming at 4K – something you’d expect to be doing regularly on a high-end prebuilt like those included in this roundup. In fact, if you’re spending the region of $4000 on any machine, 64GB should certainly be included more often than not to take best advantage of the available budget.

In terms of video memory, we’d also recommend 10GB as the minimum for gaming at 1440p, while 4K gamers will want to look towards cards with more like 16GB of VRAM. This won’t be a problem in this roundup, with all of our system picks using the most powerful RTX 4090 graphics card and it’s 24GB of GDDR6X video memory.

For memory, we have 16GB down as the bare minimum for sub-$1500 builds, while higher-end systems should include either 32GB or 64GB.

Frequently Asked Questions

RR-Question-Mark New

Is $4000 Overkill for a Prebuilt Gaming PC?

This depends on your requirements. Users seeking top-of-the-line performance will appreciate what $4000 can help you achieve when it comes to component choices. However, if your personal use case is limited to low-resolution gaming, $4000 is going to be wasted. Professional users that also happen to game will get the most out of these prebuilt systems.

RR-Question-Mark New

Is the RTX 4090 Overkill for Gaming?

It’s not overkill for native 4K resolution gaming at a stable frame rate, especially with Ray Tracing enabled. It’s overkill if you only game at lower resolutions like 1080p and 1440p.

RR-Question-Mark New

Can I Overclock My Prebuilt Gaming PC?

Yes, but make sure to have:

  • A motherboard in the build that supports overclocking.
  • Higher quality and wattage PSU, as overclocking draws more power. 
  • Ample cooling and airflow to keep components from overheating.
