Is the RTX 5070 at $520 a better deal than the RX 9070 or 9070 XT?

Make sure the $520 card's condition and warranty are clear, since that sounds more like a private-sale or used price than a typical new retail price. If it is legitimate and works properly, I would take the 5070 and keep the savings rather than spending another $200 on the 9070 XT.

The 5070 can also be attractive if you care about efficiency. With a mild undervolt, cards in this performance range can run fairly cool and use relatively little power while still handling demanding games well.

The RX 9070 at $630 is a reasonable middle option for gaming. It offers more VRAM and generally higher performance than the 5070, so it may last longer before needing an upgrade. Still, the 5070 at $520 is better value if you are comfortable with its VRAM limitation.

At $520, the RTX 5070 is the clear value choice. That is unusually low compared with current retail pricing, so it outweighs the 9070 XT's higher performance. The main drawbacks are its lower VRAM capacity and weaker long-term headroom, but the price difference is substantial.

Under normal pricing, I would lean toward the RX 9070 XT because it is faster and has more VRAM. However, this is not normal pricing—the discounted 5070 makes it the obvious buy unless you specifically need the extra performance or memory for higher resolutions and demanding settings.
