I'm looking to replace my RTX 3060 Ti 8GB with a newer graphics card that has at least 18GB of VRAM, ideally around 20GB or more. I'm not very experienced with PC hardware, so I'd appreciate recommendations. I have a Ryzen 7 7800X3D and an ASUS TUF Gaming B860 WiFi motherboard listed, although I may have the motherboard model wrong since B860 boards generally use a different CPU socket. I'm not completely committed to Nvidia; I mainly want enough graphics memory to use higher-quality settings. My monitor is an MSI curved display with roughly a 180Hz refresh rate, but I don't think it's a 4K monitor.

For Nvidia, the realistic choices are mostly 16GB cards such as the RTX 5070 Ti or RTX 5080. Cards with more than 20GB, like the RTX 4090 or 5090, are much more expensive. Older RTX 4080 Super cards can also be worth considering if you find a good deal, but current GPU pricing is high and Nvidia's newer cards may be heavily marked up compared with their launch prices.
Before choosing a GPU, confirm your actual monitor resolution. A 180Hz refresh rate tells you how many frames the display can show, but not whether it is 1080p, 1440p, or 4K. For 1440p, a 9070 XT is a compelling value choice, while an RTX 5070 Ti or 5080 makes more sense if you specifically want Nvidia features. Also double-check the motherboard model: a B860 motherboard normally isn't compatible with a Ryzen 7 7800X3D, so one of those specifications may be incorrect.
More VRAM is useful, but it doesn't automatically make a card faster. For a strong value option, look at the Radeon RX 9070 XT, especially if you can find one around $680. It generally offers plenty of VRAM and strong performance for high-refresh 1440p gaming. Nvidia cards have advantages such as DLSS, ray tracing, and broader software support, but AMD can offer better raw performance per dollar.
I'm not opposed to AMD. I've just heard Nvidia is better, so I'm trying to understand how the two compare before deciding.

Is there any reliable way to buy Nvidia cards at MSRP, and is the jump from the 40 series to the 50 series substantial enough to justify the price? I may wait if prices are likely to come down.
