Our favorite HP Omen 30L config:

AMD Ryzen 5 5600X | RTX 3060 | 8GB RAM
The HP Omen 30L comes with all kinds of spec, including a kitted out version with a powerful RTX 3090 and 32GB of RAM. For most people that will be overkill, and this model with a Ryzen 5 CPU and RTX 3060 will be much more suitable, especially when playing at 1080p.

The HP Omen 30L can come kitted out with some serious hardware, and it delivers on performance despite some tight internals that had us worried about airflow. There are other things to love as well – its few RGB zones, fair pricing, and elegant design are much appreciated as well. While the system does allow for customization, its tight confines may make it hard to do a lot of expansions, and there’s very little that can be done to add to the cooling.

How to Shop for the Best Gaming PC

Which PC is best for gaming?

When it comes to finding the best gaming PC, your main concern is finding the right balance between your budget and gaming performance. If money is no object (or at least if you're willing to take the time to save up the money) then you can't go wrong with our top two picks, the MSI MEG Aegis Ti5 and the Alienware Aurora Ryzen Edition R10. Both pack powerful CPUs (you can also upgrade these to the latest-gen Intel Core and AMD Ryzen processors) and come with Nvidia RTX 3080 graphics cards, which is just shy of the best GPU you can get, the Nvidia RTX 3090. Both have some excellent customization options as well so you can tinker around with the specs to your liking.

If you do have to mind your budget somewhat, then the HP Omen 30L is a great choice, since it has a wide range of customization options, that can give you excellent performance for the price. There's also the Lenovo Legion Tower 5i with an RTX 3060, which is about the best gaming pc you can find for 1080p and 1440p gaming at a great price.

What should you look for when buying a new gaming PC?

While building a PC for gaming can be pricey or a bit of a hassle, excellent gaming PCs are more affordable than ever before. Even the Intel Comet Lake and AMD Ryzen 5000 chips, as well as the Nvidia Ampere or Big Navi GPUs, are more accessible than their predecessors, price-wise. So, don’t stress out over the cost so much. Whatever your budget, guaranteed you won’t have to compromise as much as you would think.

Whether you’re playing the best PC games or lower-budget free games, your priority should be choosing something that manages to be affordable to you without compromising on performance or scrimping on vital features like a healthy port selection and appealing RGB lighting. That could very well mean a pricey desktop PC that will see you through 4K gaming  or one of the best budget gaming PCs that will give you a smooth 1080p gaming experience. Don’t worry so much about the frills and the design unless your budget is flexible or you’ve got deep pockets.

Make sure that there’s also enough speedy RAM and fast storage. These days, an 8GB DDR4 memory is the minimum, but upgrade to 16GB if you can. Plenty of SSD storage is ideal as well, since many top titles take up a lot of space, although you can always get an additional drive later down the line.

Finally, make sure you have enough money for quality peripherals as well. After all, a gaming PC is only as good as its peripherals. Only when coupled with the best gaming monitor and the best gaming keyboards will yours be the stuff of legends. 

How we test gaming PCs

A gaming PC is a big purchase that shouldn’t be taken lightly, which is why we don’t take our testing lightly either. Testing gaming PCs is always a comprehensive undertaking for us, using it to play not only the latest or hottest games, but also older yet still demanding titles as well, noting things like performance – especially in gaming – and cooling efficiency. We also run synthetic benchmarks like PCMark 10, 3DMark and Geekbench 5.

Furthermore, we take a look at its design, things like availability of ports, expandability and upgradability, RGB lighting, and accessibility that its chassis offers. For good measure, we’ll also check how it does with daily tasks, because most of us don’t only use our gaming PCs for gaming; it serves as our everyday computer as well.

We then take everything we’ve learned about the gaming PC and compare it to its price – whether or not it’s performance and features are worth that price tag, and whether or not it offers the best value to customers.
