Update October 12, 2023: Dell's deal on the Alienware Aurora R15 has shifted a bit this month. You can still save $800 on the powerful desktop with an NVIDIA GeForce RTX 4090, but the exact configurations aren't the same as when the deal first became available. The total discount on several models has gone down as well, though there are still several good deals.

The NVIDIA RTX 4090 is one of the most powerful gaming GPUs around, and right now you can get a prebuilt PC with that graphics card inside for $800 off. A Dell discount takes $800 off the Alienware Aurora R15 gaming desktop with an AMD Ryzen 9 7950X or a 13th Gen Intel Core i9-13900KF paired with an NVIDIA GeForce RTX 4090.

Buying an Alienware Aurora R15 is a great way to get the latest gaming specs at a more affordable price. Since Dell launched the Alienware Aurora R16 earlier this year, the R15 is often on sale. The newer Aurora R16 does have improved airflow and acoustics, but the Aurora R15 still has options for the latest hardware from Intel and NVIDIA.

This discounted Alienware Aurora R15 should be able to handle the best PC games. In addition to its high-end CPU and GPU combination, the AMD model of the Aurora R15 that's $800 off has 32GB of DDR5 RAM and a 2TB M.2 PCIe NVMe SSD. The Intel version has 4TB of storage and 64GB of RAM.

Some games take up over 100GB of storage. But the Aurora R15 can be upgraded, and you can likely find a solid SSD to put in yourself for less than Dell would charge to include more storage in the box. The Samsung 990 Pro is a solid choice for gaming and is currently on sale through Amazon.
