I'm considering selling my RTX 3090 while used prices are relatively high and replacing it with a newer, potentially cheaper graphics card. My system has a Ryzen 7 5700X, 64GB of DDR4-3200 memory, a B450 Tomahawk Max II motherboard, and a 1440p 240Hz monitor. I mainly play older games such as Resident Evil, Silent Hill, League of Legends, and Tekken, along with occasional newer releases like Clair Obscur: Expedition 33 and recent Resident Evil titles. I don't use LLMs or do demanding professional work in Premiere or FL Studio. Newer cards offer lower power consumption, lower temperatures, newer DLSS features, and frame generation, but many have less VRAM than the 3090's 24GB. Would selling the 3090 and moving to something like an RTX 4070, RTX 5070, or Radeon RX 9070 XT be a worthwhile upgrade, or would it mostly be a downgrade?

Since you play at 1440p and your 3090 is functioning properly, I’d keep it unless you specifically need lower power consumption, better ray tracing, frame generation, or a quieter and cooler system. Your Ryzen 7 5700X may also limit the benefit of chasing very high frame rates in some games, so a GPU swap alone might not dramatically improve 240Hz gaming everywhere.
For gaming, the RTX 3090 is still a very capable card. Most cheaper newer cards don’t provide enough extra performance to justify switching, and many have substantially less VRAM. A meaningful Nvidia performance upgrade would generally start around an RTX 4080 or higher, while the RX 9070 XT could be worth considering for better value and newer features. If your 3090 is working well, there’s no real urgency to replace it.
Selling the 3090 could make financial sense if you can get a very strong price and buy a discounted RX 9070 XT or RTX 4080-class card. You would save power and get a newer warranty, but the upgrade needs to be judged by actual performance rather than the generation number. A cheaper card that performs about the same isn’t really an upgrade.
The large amount of system RAM doesn’t replace graphics memory. Since you mainly game and don’t need 24GB for professional workloads, a newer 16GB card could still be perfectly usable, but moving from a 3090 to a similarly performing card would be more of a feature and efficiency change than a performance upgrade. This sounds more like possible FOMO over the current resale price than an urgent hardware problem.
The RTX 5070 would not be a compelling replacement. Its performance is close enough to the 3090 that you might only gain a few frames in some games, while losing half the VRAM. The RX 9070 XT offers a more noticeable performance improvement, but you should still compare its price, ray-tracing performance, and feature set before making the switch.
The lower VRAM on the 5070 is important, especially as newer games become more demanding. For a similar level of performance, keeping 24GB is a major advantage.
That makes sense. I was mainly tempted because used 3090 prices seem unusually high, but I don’t want to sell it only to end up with a sidegrade or downgrade.
