Pros

• Industry-leading processor
• Fantastic all-in-one liquid cooling system
• Beautiful graphic capabilities

Cons

• On the pricier side

First up, we have our favorite RTX 4090 gaming machine from Skytech, which just has an insane array of specs. With one of the best processors on the market, insane graphics capabilities, and a beautiful design, this really is one of the coolest gaming rigs on the market right now.

Let’s start by looking at the processor, the i9-13900K. This is a 24 core processor (with 32 threads), which runs at a core frequency of 3 GHz. Under load, that can go as high as 5.8 GHz, which is almost a 100% increase in speed and more than enough horsepower to smash any AAA title.

And, with the RTX 4090 on board, you’ll be able to get the kind of visual fidelity you could previously only dream about! This beautiful GPU has 24GB of GDDR6 RAM, and a bandwidth limit of 1,008 GBPS, meaning that it has the resources and speed to present any new game at ultra settings.

In terms of the machine’s other specs, there’s 32GB of the latest DDR5 RAM here. This is going to be future-proofed for some time, since demanding titles like Hogwarts Legacy and Red Dead Redemption 2 only recommend 16GB and 12GB, respectively, for the smoothest gaming experience.

The build itself is presented in a beautiful, clean white case with a mesh front. The RGB internals can all be customized using SignalRGB, meaning you can set it to match any environment. The all-in-one liquid cooling system will also provide a reliable and quiet way to keep this machine at ambient temps.

We know that an RTX 4090 gaming machine is no small investment right now, but this build from Skytech is an absolute beast, and we’d heartily recommend it to anyone who just wants to download their games and play them all at maximum settings for a good couple of years at least.

Pros

• Plenty of RAM
• Top-of-the-range graphics
• Stylish design

Cons

• Can require powerful cooling capabilities

When we were putting this list together, we knew we had to find one machine that would be particularly ideal for gaming and streaming. Then we came across this beautiful Sentinel Gamer PC, and its insane specs immediately made it a top pick.

So, for its CPU, this machine has a Core i9-13900KF. The ‘KF’ suffix means that this chip has no integrated graphics, but does have the ability to be overclocked. That’s pretty insane.

If you’re wondering why that’s such a big deal, it’s because the i9-13900KF runs at a core frequency of 3 GHz, getting up to 5.8 GHz during intense processing sessions. The fact that you can push it even further (with adequate cooling, mind you!) is insane.

Again, the RTX 4090 takes care of all your graphical processing requirements, and is exponentially more powerful than GPUs which were top-of-the-line just a few years ago. With 24GB of GDDR6 ram, and clock speeds of between 2235 MHz and 2520 MHz, no titles currently available will come close to this thing’s limits.

What makes this particular machine so well-placed for gaming and streaming is the fact that it has 64GB of memory! This provides an insane capacity not just for gaming, but to play games and leave more than enough memory left over to run as many processes (like streaming) as you like.

Visually, this is a beautiful machine, with an all-black, brushed-metal case, and a tempered glass side panel. The mesh covering on the front is mostly hidden by a front door which can open to reveal an input/output panel and provide improved cooling, too.

What more can we say? If you’re serious about streaming and have the budget for it, we can’t recommend this machine enough. It will allow you to play AAA titles at maximum settings while broadcasting to your viewers without a hitch, and we can’t think of a more-important metric than that.

Today’s last selection combines incredible performance at a price point that we feel is particularly reasonable. If you’re looking to get the best bang for your buck, then we have to go with this incredible rig from CyberPowerPC.

Again, we start with the i9-13900KF. Base frequencies of 3 GHz go up to 5.8 GHz, so games like Hogwarts Legacy, Cyberpunk 2077, and Microsoft Flight Simulator are going to have more than enough power to run very smoothly on this Raptor Lake CPU.

Then, for the GPU, we’ve still got the RTX 4090 24GB. This isn’t just an iterative update from Nvidia, but a true demonstration of what the next generation of gaming will be. With over 16,000 shading units and 128 ray tracing cores, you’re going to be able to access some of the most beautiful visuals currently available in gaming.

For memory, the machine has 16GB, which is more than adequate for any currently available AAA game at maximum settings. Storage-wise, there’s a 2TB PCI-E NVMe SSD, which will access your data incredibly quickly, silently, and reliably.

Aesthetically, this is one of the cooler gaming rigs we’ve seen, especially if you like all-white computers. The patterned front panel is unique and eye-catching, the tempered-glass side panel allows you to view its vibrant and beautiful internals, and the top of the case features a mesh section for further improved cooling.

If you’ve been saving up for a great gaming machine, you really don’t need to look any further than this offering from CyberPowerPC. With the beauty of a well designed piece of furniture, the processing power of the best gaming PCs on the market, and a very fair price-tag, you can’t go far wrong with this!
