Old GPUs Are Cashing In as RAMageddon Pushes Used RTX 3090 Prices Past $1,300

Six years is normally a death sentence for a graphics card’s resale value. Not this time. Used Nvidia RTX 3090 cards, a 2020 release, have gone from roughly $600 to $800 on the secondhand market in March to a tracked eBay range of $1,287 to $1,411 by early September, according to used-GPU data site ResalePrices, which bases that figure on 301 active US listings as of September 4, 2026.

Why a 2020 Card Is Suddenly Worth Nearly What It Cost New

The RTX 3090 launched at $1,499. The RTX 3090 launched at $1,499 in 2020 — and five years later it’s selling used for over $1,000, with 24GB of GDDR6X VRAM the reason why, since running large language models locally requires VRAM, Howard Resource Group’s market analysis noted back in May. That was already a strange outcome for a five-year-old gaming card. It’s gotten stranger since.

Back in March, XDA Developers was still calling the 3090 a bargain. It has a whopping 24GB of VRAM, can be bought for $600–$800 on the used market, and still boasts great performance for most local AI tasks, the outlet wrote at the time. Half a year later, that $600 floor is closer to $1,300, and GPU tracker GPUDojo lists the current used price starting at $1,450 as of September.

Enthusiast forums have been trading theories on how far this goes before it stops making sense to buy secondhand at all:

RAMageddon: The Memory Shortage Nobody Saw Coming

The root cause isn’t crypto mining or scalper bots this time. It’s memory, plain and simple. AI data centres are hoovering up the same DRAM, GDDR and HBM wafers that used to go into consumer graphics cards, and manufacturers have followed the money. AMD has even flagged it to investors directly. “There is currently an industry-wide memory shortage as the demand for such components has outpaced supply,” the company wrote in a recent risk statement, while board partner Zotac reportedly warned that “the very survival of graphics card manufacturers” is now at stake.

New cards have absorbed most of the pain. Market researcher TrendForce has tracked 15-20% price increases specifically on RTX 50-series cards carrying 16GB of VRAM or more, and it’s not a minor market quirk. A UK retailer’s warning from late 2025 turned out to be an understatement rather than hype. “NOW IS THE TIME TO BUY your GPU, as 2026 will see price increases,” Overclockers UK told PC Gamer back then. Tom’s Guide has documented the fallout on the shelf: it’s virtually impossible to find popular graphics cards like the RTX 5070 Ti at its original $749 price, or find it at all. That squeeze on new stock is exactly what’s pushing buyers toward the used bins.

It’s Not Just the 3090, Either

The effect cascades down the whole used lineup, not just Nvidia’s old flagship. Analysis from GPU market tracker gpupoet.com found budget GPUs like the RTX 3060, 3080 and 4060 rising in price because buyers can’t justify RTX 50 pricing, while high-end last-gen cards like the RTX 4070 Ti and 4070 Super are actually falling as RTX 50 stock gets closer to MSRP. It’s a genuinely split market: cheap cards holding value, expensive last-gen cards losing it, and anything with a big VRAM buffer defying the usual depreciation curve entirely.

AI hobbyists are a big part of why the 3090 specifically refuses to get cheaper. One recent market breakdown pointed to a straightforward chain reaction: RTX 5090 prices went up sharply within the span of about a week, and that pressure pulled 4090 and 3090 prices up with it as buyers who can’t get or afford a 5090 shift down to the next tier, with the 3090 long a favourite in the local LLM community for its 24GB of VRAM at a relatively accessible price. Every step up the ladder gets more expensive, so demand keeps landing on whatever’s one rung down.

What This Actually Means If You’ve Got an Old Card in a Drawer

If you’re sitting on a 3090, 3080 or even a 3060 you haven’t touched since your last upgrade, this is not the year to assume it’s worthless. Our view: sell into strength if you don’t actually need the VRAM for AI tinkering, because nobody credible is predicting this shortage eases before 2027, and a card that’s briefly worth close to its original launch price is not a normal event in PC hardware. Analysts cited by industry trackers expect memory supply to stay tight through the rest of 2026 at minimum, with some suppliers warning constraints could run for years given how much capacity is now locked into AI production.

None of this makes new GPUs cheaper. It just means the calculus on selling an old one has flipped. A card bought for $1,499 in 2020 that still fetches over $1,300 used in September 2026 isn’t depreciation working as usual. It’s a shortage in a completely different part of the supply chain reaching back and rewriting what your old hardware is worth.
