Gigabyte GeForce RTX 3080 Gaming OC 10GB GDDR6X

The RTX 3080 Gaming OC posts a 25,003 PassMark score with thermals in the 92nd percentile, which is excellent for a 320W card. But efficiency is in the 33rd percentile and user sentiment sits at just 45th, with owners reporting stability concerns and recommending an 850W PSU. At $400 it's a decent budget buy, at $530 it's a pass.

Let's talk numbers. The 25,003 PassMark score puts this card in the 66th percentile for rasterization, which sounds middle-of-the-pack until you remember we're comparing against cards like the RTX 5070 Ti and RX 9070 XT. For a card from the Ampere generation, that's still a lot of horsepower. The 30.64 FP32 TFLOPS of compute lands at the 77th percentile, and ray tracing performance sits at 74th, which means this thing still handles RT workloads better than most cards in our database.

The cooling is the real standout. Thermal performance at the 92nd percentile means the triple-fan Windforce design is doing serious work, keeping a 320W card from turning into a space heater. The 912 GB/s memory bandwidth is also nothing to sneeze at, and with 2x HDMI 2.1 plus 3x DisplayPort 1.4a, you can drive four monitors without breaking a sweat. The efficiency story is less rosy though, at the 33rd percentile. Ampere was never known for sipping power, and this card drinks like it's at an open bar.

Against the ASUS TUF RTX 5070 Ti, this card gets absolutely smoked in raw performance, the 5070 Ti is a generation newer with more VRAM and better efficiency. But it also costs significantly more. The MSI Suprim RTX 5080 is in a completely different league, and the ZOTAC SOLID SFF OC and PNY OC 5070 Ti variants all outclass this card in compute and efficiency. Where the 3080 Gaming OC holds its own is in thermals, that 92nd percentile cooling is better than a lot of newer cards manage. If you're on a strict budget and find one at the $400 end of the range, it's a reasonable stopgap. If you're paying $530, save a bit more and get something current.

Pricing on this renewed card is all over the place. US listings range from $400 to $530, which is a $130 spread for what should be the same product. At $400, this is a compelling budget option for 1440p gaming, especially given the 76.4/100 budget score. At $530, you're getting into territory where a used RTX 4070 or a discounted newer card starts looking more attractive. The affordability percentile sits at 57, which is about average for this class, but the renewed nature of the card means you're trading price for peace of mind. Amazon's Renewed Guarantee helps, but it's not the same as a fresh warranty from Gigabyte.

The Gigabyte RTX 3080 Gaming OC pulls a PassMark G3D score of 25,003, which lands it in the top third of our database for raw raster performance. That's a card that still handles 1440p high-refresh gaming without breaking a sweat, and it's got the VRAM bandwidth to back it up at 912 GB/s across a 320-bit bus. The 8704 CUDA cores and 1800MHz boost clock are the real story here, and the triple-fan Windforce cooler keeps thermals in the 92nd percentile, which is genuinely impressive for a card pulling 320W.

But here's the thing: this is a renewed card, and the user sentiment score sits at just 45th percentile. That's not a knock on the silicon itself, it's a knock on the buying experience. Some owners report weird graphics glitches that are hard to pin down, and the 320mm length means you'll need a case with real clearance. The 10GB of VRAM is also starting to feel tight in 2025, landing at the 56th percentile, which is fine for 1080p and most 1440p titles but not exactly future-proof for 4K texture packs.

If you're running a smaller case or a 750W power supply, this card is going to be a headache. The 320mm length and 2.7-slot width rule out compact builds, and the 33rd percentile efficiency means you'll feel the heat and the power bill. The 10GB of VRAM at the 56th percentile is also a real limitation if you're targeting 4K or planning to keep the card for several years. And honestly, if you're paying the $530 end of the price range, you're overpaying for renewed hardware with a 45th percentile user sentiment score. The mixed reliability reports from owners suggest this is a card for people comfortable troubleshooting, not for someone who wants plug-and-play peace of mind.

The Gigabyte RTX 3080 Gaming OC is a capable card held back by its age and its renewed status. The 25,003 PassMark score and 92nd percentile thermals are genuinely impressive, and at $400 it's a solid budget pick for 1440p gaming. But the 33rd percentile efficiency, 56th percentile VRAM, and mixed user sentiment at the 45th percentile mean this is a card you buy with your eyes open. The 320W power draw and reports of needing an 850W PSU for stability are real considerations. If you find one at the low end of the price range and have a big case with a beefy PSU, it's worth considering. Otherwise, the newer competition makes this a harder sell.
