For creative and AI workloads, this is the RTX 5090 PC to get in the sales, with the HP Omen 45L now $2740 (was $3230) at HP.
The savings are significant, but the real reason to buy this is the package itself: RTX 5090, Core Ultra 9 285K, HP’s patented Cryo Chamber cooling, and a system designed from the ground up to sustain flagship performance for years.
The Intel Core Ultra 9 285K is Intel’s current flagship desktop processor that makes a real difference in video production, 3D rendering, software compilation, and AI workloads. It even includes Intel’s NPU, qualifying the OMEN 45L as an AI PC for Windows 11 Copilot+ features.
Today’s top computer deal
The RTX 5090 desktop GPU in this machine is the full-fat desktop version — not the mobile variant found in laptops. With 32GB of GDDR7 memory and the complete GB202 die, it has meaningfully more CUDA cores and higher clock speeds than the laptop RTX 5090.
HP’s patented Cryo Chamber is the key differentiator in the 45L chassis. Unlike most pre-built towers that use a standard air cooler or a third-party AIO bolted onto a standard case, the Cryo Chamber is purpose-built for this chassis — it uses a dedicated cooling chamber that physically isolates the CPU and its heat management from the rest of the components. The result is consistent temperatures during sustained workloads without the fans having to ramp to uncomfortable levels. Multiple reviewers across the GT22 generation have specifically called out thermal management as a standout strength.
The built-in LCD display panel inside the chassis is a characterful touch. You can load it with custom images, GIFs, or system monitoring readouts, and it’s one of those details that HP has executed better than most — it feels like a premium extra rather than a gimmick. The overall chassis design is clean and understated compared to some more overtly aggressive gaming PC aesthetics, which makes it a better fit for a living room or shared space.
Connectivity covers the practical bases: Thunderbolt 4 at 40 Gbps on the rear, 2.5 GbE wired Ethernet, Wi-Fi 6E wireless, and a front panel with USB Type-C and USB Type-A ports for quick peripheral access. One honest caveat from reviewers: this configuration ships with 1TB SSD, which is tight for a high-end gaming machine given modern game install sizes — adding a second NVMe drive early is a sensible first upgrade, though note that accessing the second M.2 slot requires removing the GPU.
