HP’s Omen range is aimed at gamers, but a specced-out gaming PC also has everything you’ll need for serious creative work, so it’s worth looking at if you’re in the market for a Windows PC that can take on a heavy processing load. The 13th-gen Intel chip at the heart of the Omen 45L may not be the absolute latest for 2024, but it has enough cores, RAM and fast storage potential to blast through rendering and video work (and making it a fantastic high-end option for one of the best computers for graphic design and best PCs for video editing). You can even play games on it too.
