If you want to buy the cheapest possible RTX 4090 prebuilt gaming PC, then take a look at Alienware's Aurora R16 offer—at a cent shy of $3,000 you honestly won't find anything cheaper. Never one to back away from a challenge, I've been hunting through the Black Friday PC gaming deals to see if it's possible to build your own rig out of the various offers and undercut Dell's steep asking price.
Well, to cut to the chase, I couldn't. At least, not with hardware that's a match in terms of gaming performance, but I reckon I have something that's actually better, even though it's a little more expensive.

That's because all the latter has over the former are more E-cores and a higher P-core boost clock. Neither of these will matter when you're gaming at 4K with an RTX 4090.

It's the most powerful gaming graphics card money can buy and oh boy, is it a lot of money. Nothing else comes anywhere near it, though, when it comes to pushing pixels around your monitor. Plus it's comically huge and will utterly dominate the inside of your gaming rig.
And speaking of Nvidia's mightiest GPU, your only option of finding one at any vaguely sensible price is via Newegg's combo deals. The one I've picked is a Gigabyte RTX 4090
