The GeForce RTX 4090 is a generation older than the new Blackwell 50 series GPUs, but this doesn't change the fact that it's still one of the most powerful cards out there, eclipsing the GeForce RTX 5080 or RTX 4080 Super or the Radeon RX 9070 XT or RX 7900 XTX. Only one GPU performs better - the RTX 5090 - and you'll need to use up a lifetime of luck to find one that isn't marked up by hundreds, even thousands of dollars.Because the RTX 4090 has been discontinued, it's getting harder to source as well. Fortunately, Dell still sells a Alienware Aurora R16 gaming PC configuration that can be equipped with a 4090 GPU. Not only is it one of the few RTX 4090 prebuilts still available - Lenovo and HP no longer carry them - it's also one of the more reasonably priced ones.Alienware Aurora R16 RTX 4090 Gaming PC for $2,999.99Alienware Aurora R16 Intel Core Ultra 7 265F RTX 4090 Gaming PC$2,999.99 at AlienwareThis Alienware Aurora R16 gaming PC is equipped with an Intel Core Ultra 7 265F CPU, GeForce RTX 4090 GPU, 16GB of DDR5-5200MHz RAM, and a 1TB NVMe SSD. The processor can also be upgraded up to an Intel Core Ultra 9 285K. If you're getting system with a focus on gaming, then the upgrade is unnecessary. Gaming at higher resolutions is almost always GPU bound, and besides, the default Intel Core Ultra 7 265F is a solid processor with a max turbo frequency of 5.3GHz and a total of 20 cores. It's cooled by a robust 240mm all-in-one liquid cooler and the entire system is powered by an 1,000W 80PLUS Platinum power supply.Get an Upgraded Model for $3,749.99Alienware Aurora R16 Intel Core Ultra 9 285K RTX 4090 Gaming PC (32GB/2TB)$3,749.99 at DellDell also offers this upgraded RTX 4090 model for $3,749.99 with free shipping.

You also get double the RAM and storage.How does the RTX 4090 stack up against current cards?The RTX 4090 is the most powerful RTX 40 series GPU on the market. Compared to the new Blackwell cards, only the $2,000 MSRP RTX 5090 is superior in performance. This card will run every game comfortably at 4K resolution; you should be hitting 60+fps even with all settings turned to the max and ray tracing enabled, doubly so if DLSS is supported. The only setting that the 4090 (as well as every other GPU) struggles with is path tracing, but no one really ever turns this on except during benchmark tests or social media flexing. The RTX 5090 might be faster, but for the vast majority of people out there, it's just wasted power since the 4090 already excels at pretty much all things gaming.Nvidia GeForce RTX 4090 GPU Review by Chris Coke"The RTX 4090 may be huge and expensive, but holy smokes if it doesn’t blow the competition out of the water. That’s a little unfair because it’s currently the only card of this new generation that’s available, so we only have cards from the past few years to compare it to. But until the rest of the pack can catch up, between its impressive hardware specs and its DLSS 3 AI wizardry, even the $1,599 price doesn’t seem unreasonable for the unrivaled frame rates that this card can crank out."Alternative: Alienware RTX 5080 Gaming PC for $2,400Alienware Aurora R16 Intel Core Ultra 7 265F RTX 5080 Gaming PC (16GB/1TB)$2,399.99 at AlienwareDell is offering an Alienware Aurora R16 gaming PC equipped with the new GeForce RTX 5080 GPU for $2,399.99 shipped. The RTX 5080 is one of three new Blackwell graphics cards that are out (and impossible to find). In our Nvidia GeForce RTX 5080 FE review, Jackie writes that "If you already have a high-end graphics card from the last couple of years, the Nvidia GeForce RTX 5080 doesn’t make a lot of sense – it just doesn’t have much of a performance lead over the RTX 4080, though the extra frames from DLSS 4 Multi-Frame Generation do make things look better in games that support it. However, for gamers with an older graphics card who want a significant performance boost, the RTX 5080 absolutely provides – doubly so if you’re comfortable with Nvidia’s AI goodies."Check out more of the best Alienware deals.Why Should You Trust IGN's Deals Team?IGN's deals team has a combined 30+ years of experience finding the best discounts in gaming, tech, and just about every other category.
